Deconstructed Higgsless Models at LHC: The Top Triangle Moose

We describe a deconstructed Higgsless model in which electroweak symmetry breaking results largely from a Higgsless mechanism while the top quark mass is generated by a topcolor mechanism. The top quark mass arises from a Yukawa coupling to an effective top-Higgs which develops a small vacuum expectation value. Both the heavy partners of the electoweak gauge bosons and those for the SM fermions can be light enough to be visible at LHC.Comment: 5 pages, 3 figures; from the Proceedings of the 2010 Rencontres de Bloi

Low-Energy Effective Theory, Unitarity, and Non-Decoupling Behavior in a Model with Heavy Higgs-Triplet Fields

We discuss the properties of a model incorporating both a scalar electroweak Higgs doublet and an electroweak Higgs triplet. We construct the low-energy effective theory for the light Higgs-doublet in the limit of small (but nonzero) deviations in the rho parameter from one, a limit in which the triplet states become heavy. For small deviations in the rho parameter from one, perturbative unitarity of WW scattering breaks down at a scale inversely proportional to the renormalized vacuum expectation value of the triplet field (or, equivalently, inversely proportional to the square-root of the deviation of the rho parameter from one). This result imposes an upper limit on the mass-scale of the heavy triplet bosons in a perturbative theory; we show that this upper bound is consistent with dimensional analysis in the low-energy effective theory. Recent articles have shown that the triplet bosons do not decouple, in the sense that deviations in the rho parameter from one do not necessarily vanish at one-loop in the limit of large triplet mass. We clarify that, despite the non-decoupling behavior of the Higgs-triplet, this model does not violate the decoupling theorem since it incorporates a large dimensionful coupling. Nonetheless, we show that if the triplet-Higgs boson masses are of order the GUT scale, perturbative consistency of the theory requires the (properly renormalized) Higgs-triplet vacuum expectation value to be so small as to be irrelevant for electroweak phenomenology.Comment: Revtex, 11 pages, 7 eps figures included; references updated and three footnotes adde

Effects of Compex as a Warm up for Glenohumeral Range of Motion

Purpose: Research regarding proper upper extremity warm-up protocols remains inconclusive, especially for electrical stimulation methods like the Compex Sport Elite® unit. The purpose of this study is to evaluate the acute effects of a single treatment of the Compex® using the pre-warm-up protocol on glenohumeral range of motion compared to a standardized upper body ergometer (UBE) warm-up protocol. Methods: Thirty-five healthy, young adults completed the study (19 men, 16 women; age=22±2y; height=172.1±9.4cm; mass=71.3±16.1kg; right-hand dominant=28; left-hand dominant=7). Participants came to the research laboratory on two occasions, at least 48 hours apart. Participants were randomly assigned the order to complete an upper body ergometer protocol (UBE) and Compex Sport Elite®. All participants completed both intervention conditions. The UBE protocol consisted of five minutes of arm cycling at a perceived intensity of “somewhat hard” or 13 on the rating of perceived exertion scale. The Compex Sport Elite® protocol was based on manufacturer guidelines. Electrical stimulation was delivered for 25 minutes. Dominant arm passive glenohumeral internal rotation (IROT) and external rotation (EROT) ROM were measured before, immediately after, and 30 minutes after intervention. The average of three trials was used. The Global Rating of Change (GROC) scale was used after both post-intervention ROM measurements. Outcome measures were recorded by a researcher blinded to the interventions. Results: No significant interaction effect (λ=0.97; F(2,33)=0.54; p=0.59; ES=0.03) or main effects were observed for IROT. For EROT, no significant interaction effect was found (λ=0.88; F(2,33)=2.18; p=0.13; ES=0.12); however we found a main effect of time (λ=0.77; F(2,33)=5.03; p=0.12; ES=0.234). Follow-up pairwise comparisons indicated significant increase in EROT immediately post-intervention (1.508±.475; p=0.01) regardless of intervention. GROC values following dependent t-test resulted in no significant changes for either IROT or EROT (immediate post-intervention t34=0.72, p=0.48; 30 minutes post-intervention t34=0.59, p=0.56). Conclusions: No significant difference was found between the use of Compex® and UBE for warm-up of the glenohumeral joint. However, both interventions resulted in increased EROT immediately following application of intervention. Clinicians should select an intervention appropriate to meet patient goals, which may include a range of interventions or activities

Athletic Trainers’ Knowledge of Legal Practice within Information Technology and Social Media

Purpose: As healthcare and technology continue to connect in daily practice, athletic trainers (ATs) must be knowledgeable of the governing acts for ethical and legal clinical practice. This is vital to ensure ethical and legal practice as a clinician and protection of confidential protected health information (PHI). The objective of this study was to assess certified athletic trainers’ knowledge of regulations within technology and social media (SoMe). Methods: Certified ATs were recruited from the National Athletic Trainers’ Association membership database. Respondents completed an instrument of 28 questions, including 16 participant demographics, clinical site demographics, SoMe usage and general questions, and a 12-item knowledge assessment tool on a web-based survey platform. Validity of the instrument was determined through a Delphi panel of experts in athletic training, healthcare lawyers and an information technologist. We analyzed data using descriptive statistics. Results: Respondents reported a Master’s degree as their highest earned (n=106, 72.6%) with 33.6% of those degrees being at the professional level (n=49). Respondents predominately worked in the public secondary school setting (n=43, 29.5%) and worked 8-9 hours per day (n=78, 53.4%). Respondents self-reported an average of five active SoMe accounts with Facebook® (n=120,, 81.6%), LinkedIn® (n=75, 51%), Instagram® (n=70, 47.6%), Twitter® (n=70, 47.6%), Pinterest® (n=64, 43.5%), and Snapchat® (n=64, 43.5%) being the most common sites. Within their athletic training clinic, respondents predominately reported (n=76, 51.7%) that all their computers had a virtual private network, and had a SoMe policy that was enforced to some extent (n=63, 42.9%). Respondents (n=136, 92.5%) stated that they have not reported someone for a breach of HIPAA, and have not been reported themselves (n=146, 99.3%); however, respondents (n=16, 10.8%) indicated they had one or more full faced photos of patients on their SoMe accounts, breaching HIPAA. The majority of respondents have had formal education on HIPAA regulations (n=115, 78.2%). On the knowledge assessment, Respondents correctly scored 7.7±1.9 out of 12 possible points (mean score=59.2±14.5%). Conclusions: Respondents lacked the appropriate knowledge regarding HIPAA and Health Information Technology for Economic and Clinical Health (HITECH) Act regulations, and application of this knowledge within SoMe. Future research should focus on educational interventions of technology advancements for safe and legal practice as an AT

Lower Extremity Musculoskeletal Screening Tool Practices Among Athletic Trainers in Secondary School and Collegiate Settings

Purpose: Musculoskeletal (MSK) screening tools can allow athletic trainers (AT) to focus prevention efforts by providing patient risk information. The purpose of this study is to examine lower extremity MSK screening tool practices and perceptions of ATs in traditional settings. Methods: A cross-sectional online survey was distributed to 4,937 full- and part-time collegiate and secondary school ATs randomly selected by the NATA. MSK screening tools were grouped into 7 categories: Range of Motion (ROM), Strength, Balance, Drop and Jump Landing (D/J Land), Double- and Single-Leg Hopping (D/S Hop), Movement Quality (MQual), and Injury History (History). For each screening tool category, questions assessed MSK screening tool usage, the perceived effectiveness of MSK screening tools to provide relevant injury risk and return to play (RTP) information, and MSK screening tools effect on decisions to implement prevention programs. Results: A total of 372 participants (female=215(48.4%), male=152(34.2%), age=35±10 years, experience=12±10 years, secondary school=194(52.2%), collegiate=178(47.8%)) completed the survey. Participants within our study indicated the used of the following screening tools categories in clinical practice: ROM=339(91.1%), Strength=342(91.9%), Balance=238(64.0%), D/J-Landing=134(36.0%), D/S-Hopping=233(62.6%), MQual=212(57.0%), History=316(85.0%), and None=18(4.8%). Conclusions: ATs in traditional settings indicate that they primarily use ROM, Strength, and History screening tools to gather information concerning LE injury risk and RTP. Implementation of screening tools most frequently occurred post-injury. Lastly, it seemed that intervention prescriptions were consistent regardless of screening tool used, suggesting blanket interventions prescription. This may have been do feelings of moderate effectiveness of these tools to determine injury risk

Discovering New Gauge Bosons of Electroweak Symmetry Breaking at LHC-8

We study the physics potential of the 8TeV LHC (LHC-8) to discover, during its 2012 run, a large class of extended gauge models or extra dimensional models whose low energy behavior is well represented by an SU(2)^2 x U(1) gauge structure. We analyze this class of models and find that with a combined integrated luminosity of 40-60/fb at the LHC-8, the first new Kaluza-Klein mode of the W gauge boson can be discovered up to a mass of about 370-400 GeV, when produced in association with a Z boson.Comment: PRD final version (only minor refinements showing the consistency with new LHC data), 11 pages, 5 Figs, 2 Table

Z to b bbar and Chiral Currents in Higgsless Models

In this note we compute the flavor-dependent chiral-logarithmic corrections to the decay Z to b bbar in the three site Higgsless model. We compute these corrections diagrammatically in the "gaugeless" limit in which the electroweak couplings vanish. We also compute the chiral-logarithmic corrections to the decay Z to b bbar using an RGE analysis in effective field theory, and show that the results agree. In the process of this computation, we compute the form of the chiral current in the gaugeless limit of the three-site model, and consider the generalization to the N-site case. We elucidate the Ward-Takahashi identities which underlie the gaugeless limit calculation in the three-site model, and describe how the result for the Z to b bbar amplitude is obtained in unitary gauge in the full theory. We find that the phenomenological constraints on the three-site Higgsless model arising from measurements of Z to b bbar are relatively mild, requiring only that the heavy Dirac fermion be heavier than 1 TeV or so, and are satisfied automatically in the range of parameters allowed by other precision electroweak data.Comment: 19 pages, 7 embedded eps figures (additional reference added

Identifying Better Effective Higgsless Theories via W_L W_L Scattering

The three site Higgsless model has been offered as a benchmark for studying the collider phenomenology of Higgsless models. In this talk, we present how well the three site Higgsless model performs as a general representative of Higgsless models in describing W_L W_L scattering, and which modifications can make it more representative. We employ general sum rules relating the masses and couplings of the Kaluza-Klein (KK) modes of the gauge fields in continuum and deconstructed Higgsless models as a way to compare the different theories. After comparing the three site Higgsless model to flat and warped continuum Higgsless models, we analyze an extensions of the three site Higgsless model, namely, the Hidden Local Symmetry (HLS) Higgsless model. We demonstrate that W_LW_L scattering in the HLS Higgsless model can very closely approximate scattering in the continuum models, provided that the parameter `a' is chosen to mimic rho-meson dominance of pi-pi scattering in QCD

The Admissions Criteria for Professional Athletic Training Programs: A 2018 Review of Post-Baccalaureate Degrees

Purpose: Athletic training education has advanced its professional degree to an entry level masters, a decision motivated by professional health education developments over the last 10 years. In respect to Commission on Accreditation of Athletic Training Education (CAATE) accreditation standards as well as evolutionary changes in athletic training education, current prerequisite expectations of entry level applicants are largely dependent upon program. Analysis of the publicly available documents via websites and other programmatic documents of professional athletic training including prerequisite classes, supplemental admissions requirements, length and credits of program, cost of attendance and degree level of core faculty. Methods: 144 professional athletic training programs delivered at the graduate level, regardless of program design, as identified on the CAATE website in November 2018 were eligible for the analysis. Data were collected and recorded into a custom spreadsheet by one researcher regarding program characteristics, admission requirements, costs, and core faculty descriptors. Descriptive analyses were performed. Results: Most of the programs (n=96, 66.7%) were active and in good standing with the CAATE. Admissions requirements vary largely by program with 54.9% (n=142) requiring biology, 69.7% (n=142) requiring chemistry, 65.5% (n=142) requiring physics, 81.0% (n=142) requiring psychology, 99.3% (n=142) requiring anatomy, and 99.3% (n=142) requiring physiology. The average required observation hours were 48+40 with a range of 0 to 200 (n=141). Prerequisite GPA requirements varied from 2.0 to 3.40 with a mean of 2.90+0.23. Conclusion(s): Professional programs are in need of adjustment for admissions requirements to address the 2020 standards related to admissions
