Electron to selectron pair conversion in a SUSY bubble
  In the standard model, energy release in dense stars is severely restricted by the Pauli exclusion principle. However, if, in regions of space of high fermion degeneracy, there is a phase transition to a state of exact supersymmetry (SUSY), fermion to sfermion pair conversion followed by radiative transitions to the Bose ground state could lead to a highly collimated gamma ray burst. We calculate the cross section for electron to selectron pair conversion in a SUSY bubble and construct a monte carlo for the resulting sfermion amplification by stimulated emission.
