Neutrino-deuteron reactions at solar neutrino energies

Abstract

In interpreting the SNO experiments, accurate estimates of the \nu d reaction cross sections are of great importance. In our recent work, we have improved our previous calculation by updating some of its inputs and by incorporating the results of a recent effective-field-theoretical calculation. The new cross sections are slightly (\sim 1%) larger than the previously reported values. It is reasonable to assign 1% uncertainty to the \nu d cross sections reported here; this error estimate does not include radiative corrections.
