Search for point sources of neutrinos with KGF underground muon Detectors

Abstract

The proton decay detectors operated underground in the Kolar Gold Fields in India during 1980 - 1993 have recorded a large number of muon events. Out of these, 243 large zenith angle events were selected as being due to muons arising from neutrino interactions in the surrounding rock. This selection was based on the different zenith angular distributions of the atmospheric and neutrino-induced muons. These selected events are analysed to look for powerful point sources of neutrinos
