Physics & Astronomy Colloquium at CSU Long Beach


Understanding Stellar Neutrinos

Michael Smy
Department of Physics & Astronomy, UC Irvine

Monday, November 24, 2014
11:15am, HSCI-103
(Refreshments served at 10:45am in HSCI-224)

Fig: Expected νe survival probability of solar neutrinos from the MSW resonance. The solar neutrino measurements are well described by the MSW resonance, but the large uncertainties allow other possibilities such as non-standard interactions.

Neutrinos from the stars allow the study of both neutrino and stellar properties: the first observation of neutrinos from the sun simultaneously demonstrated solar power generation via nuclear fusion and provided the first hint of neutrino flavor oscillation and non-zero neutrino mass. Solar neutrinos remain an important tool to study neutrino mass, mixing, magnetic couplings, non-standard neutrino interactions as well as hydrogen burning via pp-chain or CNO cycle, solar heavy element abundance, solar core temperature etc. The observation of the neutrinos from a galactic supernova might reveal non-linear neutrino self-interactions, the neutrino masshierarchy, as well as initial neutronization, the supernova explosion mechanism, black hole formation etc.

Colloquia are scheduled to start Mondays at 11:15am sharp in Peterson Hall 2, Room 110 (PH2-110, map). Refreshments are served from 10:45am to 11:05am in Room HSCI-224 (next to the department office) and everyone is invited to mingle with faculty and students!
