New supernova limits on secret neutrino interactions


Our paper on new limits on new, secret, neutrino-neutrino interactions beyond the Standard Model from core-collapse supernovae is out:

Core-collapse supernovae stymie secret neutrino interactions (1912.09115)
Shashank Shalgar, Irene Tamborra, Mauricio Bustamante


We find limits on the mass and coupling of the new mediator through which the secret interactions occur.  For mediator masses between 10 MeV and 15 GeV, our limits are the strongest to date.  For mediator masses above 100 MeV, our limits are the first.
