Bose-enhanced Neutrino Decays in a Thermal Medium
Yuber F. Perez-Gonzalez, Manibrata Sen, Walter Tangarife
We compute the decay width of neutrinos in a thermal medium using finite-temperature quantum field theory, focusing on non-standard decays into lighter neutrinos and a scalar or li…

Heavy dark matter in rapidly evolving massive stars
Sandra Robles, Walter Tangarife, Giorgio Busoni
We study the impact of heavy dark matter (DM) captured in massive stars via scattering(s) with the star constituents. We focus on the first stars and use stellar evolution simulati…

The neutrino force in neutrino backgrounds: Spin dependence and parity-violating effects
Mitrajyoti Ghosh, Yuval Grossman, Walter Tangarife +2
The neutrino force results from the exchange of a pair of neutrinos. A neutrino background can significantly influence this force. In this work, we present a comprehensive calculat…
