Nonstandard interactions and interference effect in low energy   {\nu}_{e}e-scattering process
  We calculated the size and sign of interference (I) in elastic {\nu}_{e}e-scattering process in the presence of nonstandard neutrino interactions (NSI). The size of interference predicted by standard model (SM) is -1.09, while that measured in the LSND experiment is -1.01\pm0.18. Using the current bounds on NSI from the literature,we get I= -1.02, which is compatible with experiment . The result indicates that nonstandard current interferes constructively with the charge and neutral currents (CC and NC) of the SM, while the over all -ev sign (distructive) indicates that the dominant contribution is still from the SM, yet we can not ignore the contribution of NSI, as it enhances our knowledge in terms of known physical phenomena. As an offshoot of this analysis, the best bounds on NSI coupling parameters could be chosen.
