    Physics Colloquium

    "Precision measurement of neutrinos at Hyper-Kamiokande"

    Presented by Akira Konaka, TRIUMF

    3:30 pm, Large Seminar Room, Bldg. 510

    Tuesday, February 26, 2019, 3:30 pm

    Hosted by: Milind Diwan

    Hyper-Kamiokande (HyperK) is a water Cherenkov neutrino detector whose construction in Japan was recently approved. The fiducial mass is 187kton, eight times larger than the Super-Kamiokande detector. The upgraded J-PARC accelerator located 295km away will provide high intensity neutrino and anti-neutrino beams tuned at the oscillation maximum. In this talk, I will describe the challenges of the systematic uncertainties in future neutrino oscillation experiments and how HyperK plans to address them. In addition to the observation of CP violation, Hyper-Kamiokande will explore directions that may become the main research topic in the future if something new is discovered: Precision neutrino oscillations to test the unitarity of the lepton flavour mixing, neutrino astronomy, such as supernova neutrinos and searches for astrophysical point sources of neutrinos, and searches for phenomena beyond the standard model, such as dark matter and nucleon decays.

    Liquid Argon Time Projection Chamber (LArTPC), with its mm-scale position resolution and the full-active-volume imaging-aided calorimetry, is an excellent device to detect accelerator neutrinos at GeV energy range. This technology may hold the key to search for new CP violation in the lepton sector, to determine the neutrino mass hierarchy, to search for baryon number violation, and to search for sterile neutrino(s). In this talk, I will review the existing achievements and current status of the detector development.

    Presented by Xianyi Zhang, Illinois Institute of Technology

    PROSPECT, Precision Reactor Oscillation and SPECTrum, is a short baseline reactor antineutrino experiment. The PROSPECT antineutrino detector is an optically segmented liquid scintillator detector deployed ~7 m from a highly enriched U-235 reactor. This detector was designed to investigate discrepancies in the reactor antineutrino flux and spectrum by model-independently probing the eV-scale sterile neutrino oscillation from nuclear fission reactor, as well as precisely measuring the U-235 antineutrino spectrum. The particle multi-segment scattering in PROSPECT detector brought a typical challenge in characterizing the scintillator nonlinearity. This talk details the energy scale study for PROSPECT with data-MC comparison of detector calibrations. The detector construction, commissioning, and its early physics measurements are also presented.
