Model Independent Constraints on Solar Neutrinos

By Lal Singh, Bhag C. Chauhan, Ravi Dutt, K. K. Sharma and S. Dev


Using the data from SNO NCD phase, SuperK, Borexino and KamLAND Solar phase, we derive in a model independent way, bounds on the possible components in the solar neutrino flux. We update the limits on the antineutrino ($\bar\nu_x$) flux and sterile ($\nu_s$) component and compare them with the previous results obtained using SNO Salt phase data and data from SuperKamiokande experiments. It is affirmed that the upper bound on $\bar\nu_x$ is independent of the $\nu_s$ component. We recover the $\nu_s$ and $\bar\nu_x$ upper bounds existing in the literature. We also obtain bounds on $f_B$, the SSM normalization factor and the common parameter range for $f_B$ and the $\nu_s$ components in the light of latest data. In summary, we update, in a model independent way, the previous results existing in literature in the light of latest solar neutrino data.Comment: 21 pages, 3 figures and 13 table
