Neutrino physics
Over more than a decade, the IceCube Neutrino Observatory has accumulated enormous datasets of neutrinos with energies in the GeV to PeV-scale, opening a new window with which to observe the Universe. In this talk I will discuss the latest IceCube results, and provide a look forward of what to expect from the next generation of neutrino telescopes including the Canada-based Pacific Ocean...
The Hyper-Kamiokande (Hyper-K) project plans to measure the phenomenon of neutrino oscillations with high precision, which may give us unprecedented insight into the matter-antimatter asymmetry in our universe. For this measurement, multiple water Cherenkov detectors will be deployed that will use a new detector technology called multi-photomultiplier tubes (mPMTs). These mPMTs each consist of...
We show that, in a $U(1)_{R-L}$-symmetric supersymmetric model, the pseudo-Dirac bino and wino can give rise to three light neutrino masses through effective operators, generated at the messenger scale between a SUSY breaking hidden sector and the visible sector. The neutrino-bino/wino mixing follows a hybrid type I+III inverse seesaw pattern. The light neutrino masses are governed by the...
Neutrinoless double-beta decay ($0\nu\beta\beta$) is a hypothetical, Standard-Model forbidden nuclear process in which two beta decays occur simultaneously without the emission of antineutrinos. Its observation would imply the Majorana nature of neutrinos, proving that they are their own antiparticles, and provide critical insight into the origin of the matter-antimatter asymmetry in the...
The Water Cherenkov Test Experiment (WCTE) is a test experiment at CERN designed to enhance the sensitivity and calibration techniques of the Hyper-Kamiokande experiment. It provides a vital platform for developing calibration methods by exposing detectors to particle fluxes with well-defined types and kinematic properties. The particle identification system of WCTE comprises several detector...
