Gallium data variability and KamLAND

Abstract

We present an alternative fit to the conventional solar+KamLAND one which takes into account the possible time dependence of the Ga data and relies on the partial conversion of active $\to$ sterile neutrinos via the magnetic moment/solar field interaction. We evaluate the prediction for the solar neutrino rates obtaining a fit of similar quality as the LMA one. We also evaluate the KamLAND antineutrino survival probability as a function of reactor distance and find a better agreement with data as compared to LMA.
