We find that gamma > 7.4 10^(-22)GeV if alpha < 2 gamma and alpha > 1.5 10^(-21)GeV if alpha > 2 gamma, this limit is consistent with the upper limits extract from the K0-K0bar system and can be detected in the future experiments.10 pages, Latex fileHigh Energy Physics - PhenomenologyA Constraint on EHNS Parameters from Solar Neutrino Problemtext
