SN1987A - a Testing Ground for the KARMEN Anomaly
arXiv:hep-ph/9912465 · doi:10.1016/S0370-2693(00)00489-5
Abstract
We show, that SN1987A can serve as an astrophysical laboratory for testing the viability of the assertion that a new massive neutral fermion is implied by the KARMEN data. We show that a wide range of the parameters characterizing the proposed particle is ruled out by the above constraints making this interpretation very unlikely.
