摘要：

We perform model independent and model dependent analyses of solar neutrino data including the neutral current event rate from SNO. The inclusion of the first SNO NC data in the model independent analysis determines the allowed ranges of B-8 flux normalisation and the nu(e) survival probability more precisely than what was possible from the SK and SNO CC combination. We perform global nu(e)-nu(active) oscillation analyses of solar neutrino data using the NC rate instead of the SSM prediction for the 8B flux, in view of the large uncertainty in the latter. The LMA gives the best solution, while the LOW solution is allowed only at the 3sigma level. (C) 2002 Published by Elsevier Science B.V.
