Title: Neutral-current reactions of solar and supernova neutrinos on deuterium

Abstract

We calculate the cross sections for the neutral-current disintegration of deuterium by neutrinos and antineutrinos: ..nu..+d..--> nu..'+n+p and nu-bar+d..-->..nu-bar'+n+p. We put special emphasis on estimates of the theoretical uncertainties of these cross sections. For /sup 8/B and hep solar neutrinos, the averaged cross sections are = 4.1(1 +- 0.1) x 10/sup -43/ cm/sup 2/ and = 1.15(1 +- 0.1) x 10/sup -42/ cm/sup 2/, respectively, where hep denotes /sup 3/He+p. The cross-section uncertainty is negligible, +- 1/2%, for the ratio of neutral-current to charged-current events. Independent of neutrino oscillations, the cross sections correspond to 4.5(1 +- 0.38) x 10/sup 3/ solar-neutrino events per year in the proposed one-kiloton Sudbury Neutrino Observatory if the standard solar model is correct. For a galactic supernova, the total number of neutral-current events expected in the Sudbury detector is about 10/sup 3/ (distance/8 kpc)/sup -2/; most of the signal is expected to arise from ..mu.. and tau neutrinos and antineutrinos. If either ..mu.. or tau neutrinos have a mass greater than 2 x 10/sup 2/ eV, then this mass should be measurable using the neutrino signal from a galactic supernova.
