The differential cross-sections for elastic and inelastic neutrino-deuteron scattering are calculated analytically using nucleon-nucleon effective field theory. For elastic scattering, the deuteron axial form factor and the deuteron strange magnetic moment form factor are computed to next-to-leading order, including two-body currents. For inelastic scattering, two neutral current processes vd --> vnp, (v) over bar d --> (v) over bar np and one charged current process (c) over bar d --> e(+) nn are computed to next-to-leading order. These depend on an isovector axial two-body matrix element whose value is yet to be fixed by experiment. Potential model calculations by Kubodera et al. and Ying et al. are reproduced for different values of the two-body matrix element. This implies that the differences between the two potential model calculations lie in their treatment of short distance physics. The charged current to neutral current vd cross-section ratio is confirmed to be insensitive to short distance physics, and the same ratio is obtained by potential models and the calculation presented here, within 5%, for incident neutrino energies up to 20 MeV. The two-body matrix element could be fixed using the parity violating process (e) over bar d --> enp. (C) 2000 Elsevier Science B.V. All rights reserved.
