Stop decays with R-parity violation and the neutrino mass

The atmospheric and solar neutrino problems can be explained in a supersymmetric scenario where R-parity is broken bi linearly. Within this context we explore the decays of the top s quark. We find that the Rp violating decay t-bar1 → bτ can easily dominate over the Rp conserving decay t-bar1 → cκ-bar1o and sometimes also over the decay t-bar1 → bκ-bar1+. We study the implications of non-universal boundary conditions at the GUT scale
