摘要：

The most recent data of the four solar neutrino experiments - Homestake, Kamiokande, GALLEX and SAGE are analyzed and compared in the framework of the matter-enhanced neutrino oscillation mechanism (MSW effect), by including in a consistent way, together with the experimental errors, also all the uncertainties affecting Bahcall's version of the Standard Solar Model. A clear picture is seen to emerge, with only two small regions in the (sin(2)2 theta/cos2 theta, Delta m(2)) plane compatible at the 95% C.L. with the flux measurements of the four experiments: a "small angle solution" and a "large angle solution", the former clearly preferred by the data. The distortions induced on these solutions by flavour-changing neutral currents generated by non-conventional (supersymmetric) interactions are also estimated.
