Abstract

The primary physics signal events in the ICAL at INO are the νμ{\nu}_{\mu} charged current (CC) interactions with a well defined muon track. Apart from these events, ICAL can also detect other types of neutrino interactions, i.e. the electron neutrino charged current interactions and the neutral current events. It is possible to have a dataset containing mostly νe{\nu}_eCC events, by imposing appropriate selection cuts on the events. The νμ{\nu}_{\mu} CC and the neutral current events form the background to these events. This study uses the Monte Carlo generated neutrino events, to design the necessary selection cuts to obtain a νe{\nu}_e CC rich dataset. An optimized set of constraints are developed which balance the need for improving the purity of the sample and having a large enough event sample. Depending on the constraints used, one can obtain a neutrino data sample, with the purity of νe{\nu}_e events varying between 55% to 70%.
