We consider nonstandard interactions of neutrinos with electrons arising froma new light spin-1 particle with mass of tens of GeV or lower and couplings tothe neutrinos and electron. This boson is not necessarily a gauge boson and isassumed to have no mixing with standard-model gauge bosons. Adopting amodel-independent approach, we study constraints on the flavor-conserving and-violating couplings of the boson with the leptons from a number ofexperimental data. Specifically, we take into account the(anti)neutrino-electron scattering and e^+ e^- -> nu nubar gamma measurementsand keep explicitly the dependence on the new particle mass in allcalculations. We find that one of the two sets of data can provide the strongerconstraints, depending on the mass and width of the boson. Also, we evaluatecomplementary constraints on its separate flavor-conserving couplings to theelectron and neutrinos from other latest experimental results.
