Query: Solar neutrinos and the solar composition problem   Standard solar models (SSM) are facing nowadays a new puzzle: the solar
composition problem. New determinations of solar metal abundances lead SSM
calculations to conflict with helioseismological measurements, showing
discrepancies that extend from the convection zone to the solar core and can
not be easily assigned to deficiencies in the modelling of the solar convection
zone. We present updated solar neutrino fluxes and uncertainties for two SSM
with high (old) and low (new) solar metallicity determinations. The
uncertainties in iron and carbon abundances are the largest contribution to the
uncertainties of the solar neutrino fluxes. The uncertainty on the ^14N+p ->
^15O+g rate is the largest of the non-composition uncertainties to the CNO
neutrino fluxes. We propose an independent method to help identify which SSM is
the correct one. Present neutrino data can not distinguish the solar neutrino
predictions of both models but ongoing measurements can help to solve the
puzzle.
