Neutrino–deuteron reactions at solar neutrino energies

In interpreting the SNO experiments, accurate estimates of the <f>νd</f> 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 (<f>∼1</f>%) larger than the previously reported values. It is shown to be reasonable to assign 1% uncertainty to the <f>νd</f> cross sections reported here; this error estimate does not include radiative corrections, for which we refer to the literature.
