Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

Speaker: Ben Smithers (UTA)- Title: A Multi-Channel Search for Signatures of eV-Scale Sterile Neutrinos in IceCube

June 16, 2023 @ 12:00 pm - 1:00 pm

This is an In-Person [HYBRID] Event

LOCATION: Sessler CR, 50A-5132

DATE: June 16, 2023

TIME: 12:00- 1:00 PM

TITLE: A Multi-Channel Search for Signatures of eV-Scale Sterile Neutrinos in IceCube

ABSTRACT: The IceCube Neutrino Observatory is a cubic-kilometer-scale neutrino observatory built using a gigaton of instrumented ice near the Amundsen–Scott South Pole Station in Antarctica; it measures the Cherenkov light emitted by the daughter particles of neutrino-nucleon interactions occurring inside and around the detector from neutrinos of both astrophysical and atmospheric origin. For eV2-scale sterile neutrino models, matter-effects can yield resonant $\bar{\nu}_{\mu}\to\bar{\nu}_{s}$ oscillations for TeV-scale up-going neutrinos. For certain combinations of mixing angles, this is also expected to yield resonant $\bar{\nu}_{\mu}\to\bar{\nu}_{\tau}$ oscillations at the same energies and zeniths as the $\nu_{\mu}$ disappearance. This superimposed $\nu_{\mu}$ disappearance and $\nu_{\tau}$ appearance presents itself as an ideal signature with which we can search for indications of sterile neutrino oscillations. Here, we discuss a multi-channel analysis searching for signs of both resonant muon neutrino disappearance as well as tau neutrino appearance.
