Neutrinos from a standard solar model
Abstract
Solar model calculations are performed, as both (1) an independent check of the new value for the Cl-37 capture rate, and (2) an extension of the input parameters of a standard model to the extremes of experimental and theoretical limits with a view to implications for stellar evolution or neutrino physics. Capture rates are calculated for the on-line Cl-37 experiment and the proposed experiment employing Ga-71 as an example of a detector sensitive to the high-flux, lower-energy p-p neutrinos. The effects of uncertainties in the input parameters on the predicted capture rate in the two detectors are examined by: (1) calculating the effect of individual uncertainties on the mean standard model and summing these errors in quadrature; (2) simultaneously varying several key parameters to yield upper and lower limits; and (3) by generating a set of models whose parameters are determined by a Monte Carlo method.
