Constraining nonstandard neutrino-quark interactions with solar, reactor and accelerator data

Abstract

We present an analysis of nonstandard neutrino interactions (NSI) of electron and tau neutrinos with down-quark using solar, reactor and accelerator data. We include new solar data from SNO phase III and Borexino, as well as new KamLAND data and solar fluxes. We combine these results with the CHARM data allowing us to better constrain the axial and axial-vector electron and tau-neutrino NSI parameters. © 2010 IOP Publishing Ltd.
