CP Asymmetry in Charged Higgs Decays to Chargino-Neutralino

We analyze the charge-parity (CP) asymmetry in the charged Higgs boson decays to chargino-neutralino pairs, H^- -> chargino_i + neutralino_j. We show first that these modes have a large branching ratio for m_H^- > 600 GeV. We use Cutkosky rules to obtain the analytical formulas needed for the evaluation of the asymmetry under consideration. We then calculate the CP asymmetry in chargino-neutralino decays by including supersymmetric mass bounds, as well as constraints from b -> s gamma, (g-2)_mu, Delta\rho and electric dipole moments. Finally, we discuss observability of the asymmetry at the LHC by calculating the number of required charged Higgs events to observe the asymmetry for each decay channel. We show that the inclusion of constraints considerably reduces the projected CP asymmetry, and that the optimal channel for observing the asymmetry is H^- -> chargino_1 + neutralino_2.Comment: 23 pages, 8 figures, one tabl

A Standard Operating Procedure Video for Dauni Spa and Beauty House to Standardize Its Therapists' Service Qualities

Dauni Spa, the company where I did my internship, provides spa treatment, sauna, and salon service. During my internship at Dauni Spa, I found there are various practices of massage techniques performed by the therapists that lead to inconsistency in the service qualities. This problem certainly resulted in unsatisfactory treatment because the customers would not be satisfied to receive inconsistent service quality. Aside from this problem, many newly-recruited therapists did not know the standard procedures of massage in Dauni Spa while they needed to start working very soon. Therefore, I intend to make a standard operating procedure (SOP) video as a solution to the problems. For the newly recruited therapists, the SOP video can give effective and efficient instructions of the standard procedures in Dauni Spa. For the old therapists, this video works as a standard service quality that should be put into practice by all therapists. The basic content of this video is the procedures of the massage and a little background information about Dauni Spa. From this video, there are some benefits that Dauni Spa can get. It can complete the written SOP that they have, cut down the cost of a trainer, and bring a good impact to the customers' satisfaction

Payload crew utilization for spacelab missions

Planned payload crew utilization on Spacelab mission are analyzed to establish trends and guidelines. The study included missions that have flow to date as well as those in planning. Available data were analyzed on the basis of four major timeline iterations that occur during mission design. Data were categorized and assessed by crewmember, flight day, and mission. Based on the results of this analysis, it was recommended that for the Requirements Review and Preliminary Design Review iterations the maximum utilization per shift should be 75 percent for the Payload Specialist (PS) and 65 percent for the Mission Specialist (MS); and for the basic and final iterations, the maximum utilization shift should be 85 percent for the PS and 75 percent for the MS. Additional recommendations include limiting the amount of activity during the first two shifts whenever possible and establishing a common set of guidelines for the calculations of crew utilization

A Guidebook on How to Be Students in an American University for Students of Alfalink Overseas Study and English Course

In the internship program, I worked at West Alfalink which is located at Ruko Rich Palace kav. I-1 Jl. MayjenSungkono 149-151. Alfalink is an overseas education consultant / agent and English language center. In this company, I found three problems. One of them is no guidebook for students who choose the USA to do their overseas study. By looking at this condition, I decided to make the USA guidebook for Alfalink's students. It can be an effective tool for the company to give detailed information for the students. By providing this guidebook, Alfalink and students can get a lot of benefits. First, Alfalink's staff do not need to give long explanation to the students and to new staff. Second, Alfalink can use it as a promotional tool. Last, students can get complete information about the USA

Male and Female Buying Decision Making Processes Seen From BlackBerry Messenger Texts

This study observes the male and female buying decision making processes seen from BlackBerry Messenger texts. It focuses on the way of how male and female customers make a buying decision in the online shop via BlackBerry Messenger. The data are analyzed by using the theory of the consumer decision-making process by Lamb, Hair, McDaniel (2003) which includes five stages. I found that the female customers have almost two times total more than male customers in the four stages in consumer decision making process. It means, the male decision-making seems to be rational, fast, and attentive for product quality and its function. However, the female decision-making is more emotional, attentive for product surface or outside appearance, and careful for choosing a product she wants to buy. Overall, I know that gender is an important factor that makes the buying processes between both gender groups different

Large evolution of the bilinear Higgs coupling parameter in SUSY models and reduction of phase sensitivity

The phases in a generic low-energy supersymmetric model are severely constrained by the experimental upper bounds on the electric dipole moments of the electron and the neutron. Coupled with the requirement of radiative electroweak symmetry breaking, this results in a large degree of fine tuning of the phase parameters at the unification scale. In supergravity type models, this corresponds to very highly tuned values for the phases of the bilinear Higgs coupling parameter $B$ and the universal trilinear coupling $A_0$. We identify a cancellation/enhancement mechanism associated with the renormalization group evolution of $B$, which, in turn, reduces such fine-tuning quite appreciably without taking recourse to very large masses for the supersymmetric partners. We find a significant amount of reduction of this fine-tuning in nonuniversal gaugino mass models that do not introduce any new phases.Comment: Version to appear in Phys.Rev.D.

On the EDM Cancellations in D-brane models

We analyze the possibility of simultaneous electron, neutron, and mercury electric dipole moment (EDM) cancellations in the mSUGRA and D--brane models. We find that the mercury EDM constraint practically rules out the cancellation scenario in D-brane models whereas in the context of mSUGRA it is still allowed with some fine-tuning.Comment: 10 pages, to appear in Phys.
