Abstract
As is well known, the comparison of the solar neutrino fluxes measured in S uperKamiokande (SK) by v+e(-)-->v+e(-) and in the Sudbury Neutrino Observat ory (SNO) by v(e)+d -->e(-)+p+p can provide a "smoking gun" signature for n eutrino oscillations as the solution to the solar neutrino puzzle. This occ urs because SK has some sensitivity to all active neutrino flavors whereas SNO can isolate electron neutrinos. This comparison depends crucially on th e normalization and uncertainty of the theoretical charged-current neutrino -deuteron cross section. We address a number of effects which are significa nt enough to change the interpretation of the SK-SNO comparison.
