Updated determination of the solar neutrino fluxes from solar neutrino data Bergström, Johannes González García, Ma. Concepción Maltoni, Michele Peña Garay, Carlos Serenelli, Aldo M. Song, Ningqiang Neutrins solars Física de partícules Solar neutrinos Particle physics We present an update of the determination of the solar neutrino fluxes from a global analysis of the solar and terrestrial neutrino data in the framework of three-neutrino mixing. Using a Bayesian analysis we reconstruct the posterior probability distribution function for the eight normalization parameters of the solar neutrino fluxes plus the relevant masses and mixing, with and without imposing the luminosity constraint. We then use these results to compare the description provided by different Standard Solar Models. Our results show that, at present, both models with low and high metallicity can describe the data with equivalent statistical agreement. We also argue that even with the present experimental precision the solar neutrino data have the potential to improve the accuracy of the solar model predictions. 2019-12-12T10:43:30Z 2019-12-12T10:43:30Z 2016-03-18 2019-12-12T10:43:31Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 1126-6708 https://hdl.handle.net/2445/146578 669830 eng Reproducció del document publicat a: https://doi.org/10.1007/JHEP03(2016)132 Journal of High Energy Physics, 2016, vol. 2016, num. 132 https://doi.org/10.1007/JHEP03(2016)132 info:eu-repo/grantAgreement/EC/FP7/289442/EU//INVISIBLES cc-by (c) Bergström, Johannes et al., 2016 http://creativecommons.org/licenses/by/3.0/es info:eu-repo/semantics/openAccess 19 p. application/pdf Springer Verlag Articles publicats en revistes (Física Quàntica i Astrofísica)
