Abstract

We present a novel approach for constraining nonstandard neutrino interaction (NSI) coupling parameters (ε_ee^eL and ε_ee^eR) in low energy flavor conserving ν_ee and ν_ee-scattering processes. Here we exploit an important phenomenon of interference and assuming that ε_ee^eL and ε_ee^eR are same for both the processes as g_L and g_R in the standard model (SM). Using this approach we obtain the absolute values ε_ee^eL=8.7x10^-3 and ε_ee^eR=3.8x10^-1, while the bounds obtained using the said processes are -0.11
