Low reheating temperature and the visible sterile neutrino
read the original abstract
We present here a scenario, based on a low reheating temperature T_R << 100 MeV at the end of (the last episode of) inflation, in which the coupling of sterile neutrinos to active neutrinos can be as large as experimental bounds permit (thus making this neutrino ``visible'' in future experiments). In previous models this coupling was forced to be very small to prevent a cosmological overabundance of sterile neutrinos. Here the abundance depends on how low the reheating temperature is. For example, the sterile neutrino required by the LSND result does not have any cosmological problem within our scenario.

Neutrino Dipole Moments and Radiative Signatures from Partial Compositeness
Partial compositeness with inverse seesaw yields neutrino dipole moments of 10^{-6} to 10^{-8} GeV^{-1} and predicts single- and multi-photon radiative signals at MiniBooNE and MINERvA.
