| Abstract: | We give plausible interpretations of the unusual events seen in the proton decay detector at Kolar Gold Fields indicating
the existence of a massive (≳2GeV) long lived (10−8−10−9s) particle. We show that it is possible to accommodate the particle in the standard model as a fourth generation neutrino,
or inE
6 grand unified theory as a neutral fermion occurring in27 representation or in supersymmetric theory as a scalar neutrino. However, there is a difficulty in explaining the large production
rate for the particle. |
