Constraining non-standard interactions of the neutrino with Borexino.

We use the Borexino 153.6 ton·year data to place constraints on non-standard neutrino-electron interactions, taking into account the uncertainties in the ⁷Be solar neutrino flux and the mixing angle Θ₂₃, and backgrounds due to ⁸⁵Kr and ²¹⁰Bi β-decay. We find that the bounds are comparable to existing bounds from all other experiments. Further improvement can be expected in Phase II of Borexino due to the reduction in the 85Kr background.
