SN1987A - a Testing Ground for the KARMEN Anomaly

High Energy Physics - Phenomenology 2009-10-31 v3 Astrophysics

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.
