The Fable of the Unstable Neutrinos
Speaker: Srubabati Goswami (Physical Research Laboratory)Host: Doojin Kim/Bhaskar Dutta
Neutrino decay is governed by a non-Hermitian effective Hamiltonian and in general the mass eigenstates and decay eigenstates are not the same. This mismatch is inevitable in the presence of matter and the Hermitian and anti-Hermitian components cannot be simultaneously diagonalized by unitary transformations for all matter densities. In this [...]COHERENT Neutrino Program and the First Search for Neutrino-Induced Nuclear Fission
Speaker: Tyler Johnson (Duke University)Host: Doojin Kim
Over 50 years ago, it was predicted that it is possible to split an atom with a neutrino interaction, but there has never been a concerted experimental effort to confirm this phenomenon. The existence of this process would inform nuclear astrophysics, nuclear reactor monitoring and give a vantage into a [...]
