Parallel Session 2: Astrophysical Neutrinos
- Arnab Dasgupta (PITT-PACC)
The largest tau neutrino dataset to date is IceCube's atmospheric tau neutrino appearance dataset containing $>1,000$ tau neutrino and antineutrino events as determined by a fit to a standard three-flavor oscillation framework. On an event-by-event basis, however, it is impossible to know that any given event is a tau neutrino as they are identical to either an electron neutrino...
The IceCube Neutrino Observatory, a gigaton-scale Cherenkov detector located several kilometers beneath the surface of the South Pole, has detected hundreds of thousands of atmospheric neutrinos at energies from a few GeV to 100 TeV. Above 100 GeV, where ordinary oscillation effects become vanishingly small, this data sample offers the opportunity to search for and set constraints on a wide...
The IceCube Neutrino Observatory is a gigaton-scale Cherenkov telescope frozen beneath the ice at the Amundsen-Scott South Pole Station. Spanning approximately a cubic kilometer, it has detected hundreds of thousands of neutrino events at energies ranging from a few GeV to hundreds of TeV. Its high event statistics and sensitivity to a wide range of energies have given it an unprecedented...
Along with their long propagation from production to detection, neutrino states undergo quantum interference which converts their types, or flavours. High-energy astrophysical neutrinos are known to propagate unperturbed over a billion light-years in vacuum. These neutrinos act as the largest quantum interferometer and are sensitive to the smallest effects in vacuum due to new...
Fully understanding the average core-collapse supernova requires detecting the diffuse supernova neutrino background (DSNB) in all flavors. While the DSNB $\bar{\nu}_e$ flux is near detection, and the DSNB $\nu_e$ flux has a good upper limit and prospects for improvement, the DSNB $\nu_x$ (each of $\nu_\mu, \nu_\tau, \bar{\nu}_\mu, \bar{\nu}_\tau$) flux has a poor limit and heretofore had no...
The search for sub-MeV neutrinos via precision nuclear decay measurements is among the most powerful methods for BSM neutrino mass searches since it relies only on the existence of a heavy neutrino admixture to the active neutrinos, and not on the model-dependent details of their interactions. Within this context, the BeEST (Beryllium Electron-capture with Superconducting Tunnel junctions)...
