SN1987A - a Testing Ground for the KARMEN Anomaly
I. Goldman, R. Mohapatra, S. Nussinov
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.
