Scientific paper

The authors have performed a numerical investigation of the cosmion hypothesis as a solution to the solar neutrino puzzle, using the Saclay solar evolution code. The ensuing constraints on cosmion parameters appear as domains in the plane of cosmion-proton cross-section versus cosmion mass. Various hypothesis on cosmion couplings are considered. Comparison with available experimental data on direct dark matter detection excludes most of the domain in the "vector" case. In the "axial" case the results provide useful hints for experiments. Finally the effect of cosmions on the sound speed near the center of the sun is confronted with present knowledge and data on helioseismology.
