Influence of the axial-vector coupling constant on solar models - Solar neutrino fluxes, helium content and oscillations

Résumé

This paper examines the effects of axial-vector coupling constant g(A) changes on the outputs of solar-models (such as helium content, neutrino fluxes, and oscillations), using existing 'calibrated' solar models and assuming that the other inputs of the models are well-known. The results suggest that a very high value of g(A) (greater than 1.55) is required to reconcile the theoretical and observed neutrino fluxes. This value seems to be improbable with respect to the present range of measurements of g(A); moreover, a solar model with such a high value of g(A) is associated to a helium content that is above the usually accepted value.
