Stop decays with R-parity violation and the neutrino mass

The atmospheric and solar neutrino problems can be explained in a supersymm etric scenario where R-parity is broken bilinearly. Within this context we explore the decays of the top squark. We find that the Rp violating decay ( t) over tilde(1) --> b tau can easily dominate over the Rp conserving decay (t) over tilde(1) --> c<(chi)over tilde>(0)(1) and sometimes also over the decay (t) over tilde(1) --> b<(chi)over tilde>(+)(1). We study the implica tions of non-universal boundary conditions at the GUT scale.
