Abstract

Neutrino-electron scattering is a purely leptonic fundamental interaction and therefore provides an important channel to test the Standard Model (SM), especially at the low energy-momentum transfer regime [1, 2]. In this study Data on (v) over bar (e) - e and v(e) - e scattering from the TEXONO and LSND experiments, respectively, are used and constraints on neutrino Non-Stardard-Interactions (NSI) couplings depending on model-independent approaches, which are described by a four-Fermi point like interaction and depending on several beyond-Standard Model-physics scenarios, mediated by massive intermediate particles including (1) an extra Z-prime gauge boson, (2) a new light spin-1 boson (NLS1B), (3) Dark Photon (DP), and (4) a charged Higgs boson (CHB), are placed via the neutrino-electron scattering channel to test the SM at a low energy-momentum transfer regime. The relevant parameter spaces are extended by allowing light mediators.
