    Get PDF
    Millions of Californians have gained health coverage through Medi-Cal, yet many eligible for the program remain uninsured. CHCF commissioned qualitative research to better understand what prevents eligible Californians from enrolling and to identify ways California can make Medi-Cal even more accessible to the population it is designed to serve. Through virtual focus groups and in-depth interviews with 91 Californians, the research team explored the knowledge, attitudes, and enrollment experiences of people who are likely eligible for Medi-Cal yet remain uninsured

    #improveresourcesharing: Indiana Resource Sharing White Paper

    Get PDF
    This white paper calls for a series of changes to improve resource sharing in the state of Indiana. These changes include; making rare and scarcely held resources such as local history discoverable; making Indiana Evergreen’s collections discoverable and requestable by other libraries; implementing recommendations on membership in Indiana Share; adherence to best practices for resource sharing; and, recognizing that the population is mobile and that users of public libraries may also be users of academic libraries that a common brand for resource sharing be created to help users find the service at all their libraries

    The Long-Baseline Neutrino Experiment: Exploring Fundamental Symmetries of the Universe

    Get PDF
    The preponderance of matter over antimatter in the early Universe, the dynamics of the supernova bursts that produced the heavy elements necessary for life and whether protons eventually decay --- these mysteries at the forefront of particle physics and astrophysics are key to understanding the early evolution of our Universe, its current state and its eventual fate. The Long-Baseline Neutrino Experiment (LBNE) represents an extensively developed plan for a world-class experiment dedicated to addressing these questions. LBNE is conceived around three central components: (1) a new, high-intensity neutrino source generated from a megawatt-class proton accelerator at Fermi National Accelerator Laboratory, (2) a near neutrino detector just downstream of the source, and (3) a massive liquid argon time-projection chamber deployed as a far detector deep underground at the Sanford Underground Research Facility. This facility, located at the site of the former Homestake Mine in Lead, South Dakota, is approximately 1,300 km from the neutrino source at Fermilab -- a distance (baseline) that delivers optimal sensitivity to neutrino charge-parity symmetry violation and mass ordering effects. This ambitious yet cost-effective design incorporates scalability and flexibility and can accommodate a variety of upgrades and contributions. With its exceptional combination of experimental configuration, technical capabilities, and potential for transformative discoveries, LBNE promises to be a vital facility for the field of particle physics worldwide, providing physicists from around the globe with opportunities to collaborate in a twenty to thirty year program of exciting science. In this document we provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess.Comment: Major update of previous version. This is the reference document for LBNE science program and current status. Chapters 1, 3, and 9 provide a comprehensive overview of LBNE's scientific objectives, its place in the landscape of neutrino physics worldwide, the technologies it will incorporate and the capabilities it will possess. 288 pages, 116 figure

    Sensitivity of the T2K accelerator-based neutrino experiment with an Extended run to 20×102120\times10^{21} POT

We explore the physics program of an extension to the currently approved T2K running of 7.8×10217.8\times 10^{21} protons-on-target to 20×102120\times 10^{21} protons-on-target,aiming at initial observation of CP violation with 3σ\,\sigma or higher significance for the case of maximum CP violation. With accelerator and beam line upgrades, as well as analysis improvements, this program would occur before the next generation of long-baseline neutrino oscillation experiments that are expected to start operation in 2026.We acknowledge the support of MEXT, Japan; NSERC (Grant No. SAPPJ-2014-00031), NRC and CFI, Canada; CEA and CNRS/IN2P3, France; DFG, Germany; INFN, Italy; National Science Centre (NCN), Poland; RSF, RFBR and MES, Russia; MINECO and ERDF funds, Spain; SNSF and SERI, Switzerland; STFC, UK; and DOE, USA.

    Updated T2K measurements of muon neutrino and antineutrino disappearance using 1.5 x 10(21) protons on target

    We report measurements by the T2K experiment of the parameters θ23\theta_{23} and Δm322\Delta m^{2}_{32} governing the disappearance of muon neutrinos and antineutrinos in the three flavor neutrino oscillation model. Utilizing the ability of the experiment to run with either a mainly neutrino or a mainly antineutrino beam, the parameters are measured separately for neutrinos and antineutrinos. Using 7.482×10207.482 \times 10^{20} POT in neutrino running mode and 7.471×10207.471 \times 10^{20} POT in antineutrino mode, T2K obtained, sin2(θ23)=0.510.07+0.08\sin^{2}(\theta_{23})=0.51^{+0.08}_{-0.07} and Δm322=2.530.13+0.15×103\Delta m^{2}_{32} = 2.53^{+0.15}_{-0.13} \times 10^{-3}eV2^{2}/c4^{4} for neutrinos, and sin2(θ23)=0.420.07+0.25\sin^{2}({\overline{\theta}}_{23})=0.42^{+0.25}_{-0.07} and Δm232=2.550.27+0.33×103{\Delta\overline{m}^2}_{32} = 2.55^{+0.33}_{-0.27} \times 10^{-3}eV2^{2}/c4^{4} for antineutrinos (assuming normal mass ordering). No significant differences between the values of the parameters describing the disappearance of muon neutrinos and antineutrinos were observed.Comment: 8 pages, 2 figure

    Measurement of the muon neutrino inclusive charged-current cross section in the energy range of 1–3 GeV with the T2K INGRID detector

    We report a measurement of the νμ-nucleus inclusive charged-current cross section (¼ σcc) on iron using data from the INGRID detector exposed to the J-PARC neutrino beam. The detector consists of 14 modules in total, which are spread over a range of off-axis angles from 0° to 1.1°. The variation in the neutrino energy spectrum as a function of the off-axis angle, combined with event topology information, is used to calculate this cross section as a function of neutrino energy. The cross section is measured to be σccð1.1 GeVÞ ¼ 1.10 0.15 ð10−38 cm2=nucleonÞ, σccð2.0 GeVÞ ¼ 2.07 0.27 ð10−38 cm2=nucleonÞ, and σccð3.3 GeVÞ ¼ 2.29 0.45 ð10−38 cm2=nucleonÞ, at energies of 1.1, 2.0, and 3.3 GeV, respectively. These results are consistent with the cross section calculated by the neutrino interaction generators currently used by T2K. More importantly, the method described here opens up a new way to determine the energy dependence of neutrino-nucleus cross sections
