Solar Neutrinos Before and After KamLAND

We use the recently reported KamLAND measurements on oscillations of reactor anti-neutrinos, together with the data of previously reported solar neutrino experiments, to show that: (1) the total 8B neutrino flux emitted by the Sun is 1.00(1.0 \pm 0.06) of the standard solar model (BP00) predicted flux, (2) the fraction of the 8B flux that is in the form of sterile neutrinos is 0.00^{+0.09}_{-0.00}, (3) the KamLAND measurements reduce the area of the globally allowed oscillation regions that must be explored in model fitting by six orders of magnitude in the Delta m^2-tan^2 theta plane, (4) LMA is now the unique oscillation solution to a CL of 4.7sigma, (5) maximal mixing is disfavored at 3.3 sigma, (6) active-sterile admixtures are constrained to sin^2 eta<0.13 and (7) the SNO CC day-night asymmetry may be large enough to be measured, A_{N-D}(SNO CC) = 3.3^{+1.2}_{-1.0} % (1 sigma). We also refine quantitative predictions for future 7Be and p-p solar neutrino experiments.
