Neutrino-deuteron reactions at solar neutrino energies

In interpreting the SNO experiments, accurate estimates of the vd reaction cross sections are of great importance. We improve the previous estimates of our group by updating some of its inputs and by taking into account the results of a recent effective-field-theoretical calculation. The new cross sections are slightly (similar to 1%) larger than the previously reported values. It is shown to be reasonable to assign 1% uncertainty to the vd cross sections reported here; this error estimate does not include radiative corrections, for which we refer to the literature.
