On the Normalization of the Neutrino-Deuteron Cross Section

Abstract

As is well-known, comparison of the solar neutrino fluxes measured in SuperKamiokande (SK) by $\nu +e^{-}\to \nu +e^{-}$ and in the Sudbury Neutrino Observatory (SNO) by ${\nu }_e+d\to e^{-}+p+p$ can provide a ``smoking gun'' signature for neutrino oscillations as the solution to the solar neutrino puzzle. This occurs because SK has some sensitivity to all active neutrino flavors whereas SNO can isolate electron neutrinos. This comparison depends crucially on the normalization and uncertainty of the theoretical charged-current neutrino-deuteron cross section. We address a number of effects which are significant enough to change the interpretation of the SK--SNO comparison.
