Critical review of the results of the Homestake solar neutrino experiment

The radiochemical experiment in the Homestake mine was designed to measure the solar neutrino flux through the detection of $^{37}Ar$ produced in the reaction $\nu_e + ^{37}Cl \longrightarrow e^-+^{37}Ar$. The comparison between this measurement and the theoretical predictions from solar models evidences a substantial disagreement. I reanalyzed the data evidencing a bias with high statistical significance and suggesting a new interpretation of the data.
