R2-9 Neutrino experiment and related calibration (PPD) / Expérience sur neutrinos et calibration associée (PPD)
- Claire David (York University (CA))
At energies over 100 TeV, the universe becomes opaque to photons limiting the range of high energy gamma ray observations to roughly within the Milky Way. Neutrinos on the other hand do not suffer from this drawback which makes them ideal messengers for studying extremely energetic astrophysical phenomena across the cosmos. Recent observations using neutrino telescopes have thoroughly cemented...
The Hyper-Kamiokande (HK) experiment, a next generation underground experiment in Japan, will have a broad physics program, including long-baseline neutrino oscillation measurements using an upgraded 1.3 MW beam produced at J-PARC accelerator, following the successful T2K experiment. To achieve the designed goal, an accurate prediction of neutrino interaction rates on the water target at the...
A neutrino (or an anti-neutrino) can interact with an entire nucleus coherently (this means that the target nucleus has to stay intact after the interaction) and produce a pion - we call such an interaction coherent pion production. The interaction can either be mediated by a Z boson (neutral current) or a W boson (charged current). This process is not well understood theoretically. ...
Precision measurements of neutrino interactions being pursued in the current Super-K detector, the next-generation Hyper-K detector, and its Intermediate distance Water Cherenkov Detector (IWCD) necessitate improved calibrations. Photogrammetry will be used to reduce the position uncertainty on the photomultiplier tubes (PMTs) and calibration source locations within the detector. The...
SNO+ is a multipurpose neutrino experiment located approximately 2 km underground in SNOLAB, Sudbury, Canada. The second phase of the experiment is underway and consists of filling the detector with 780 tonnes of Linear Alkyl Benzene (LAB) scintillator. The fill is expected to be completed spring 2021. During this partial fill stage a number of external calibration campaigns have been...
