Probing long-range $L_e-L_\mu$ forces with supernova neutronization burst neutrinos
Ultralight gauge bosons associated with flavour-dependent leptonic symmetries generate long-range potentials that can modify neutrino flavour evolution over astrophysical distances. We investigate the sensitivity of neutronization-burst neutrinos from core-collapse supernovae for such interactions in the anomaly-free $...
