Constraining Non-Standard Interactions of the Neutrino with Borexino

摘要

We use the Borexino 153.6 ton.year data to place constraints on non-standardneutrino-electron interactions, taking into account the uncertainty in the 7Besolar neutrino flux, and backgrounds due to 85Kr and 210Bi beta-decay. We findthat the bounds are comparable to existing bounds from all other experiments.Further improvement can be expected in Phase II of Borexino due to thereduction in the 85Kr background.
