The Sensitivity of a Lithium Experiment on Solar Neutrinos to the Mixing Angle theta_{12}

Authors

Description

A lithium-based radiochemical detector is aimed primarily to detect neutrinos from CNO cycle what will provide a direct proof of its existence and will be a stringent test of the theory of stellar evolution. Another task which can be solved by this experiment is to measure a mixing angle $θ_{12}$. The sensitivity of a lithium experiment to $θ_{12}$ was calculated by Monte-Carlo following the proposed original technique which can be used as a complimentary one to a chi-square technique usually applied to this task. It is shown that the accuracy of measurement of the mixing angle in solar neutrino experiments is principally limited by the accuracy of a lithium experiment due to the limiting uncertainty of the energy generated in a pp chain.
