The study focuses on generalized neutrino interactions for various neutrino processes and constrains scalar, pseudoscalar, and tensor new physics effective couplings through a global analysis. It presents individual constraints for each effective parameter and shows robust results for the restrictions on the different GNI parameters, improving some of these bounds.
We study generalized neutrino interactions (GNI) for several neutrino processes, including neutrinos from electron-positron collisions, neutrino-electron scattering, and neutrino deep inelastic scattering. We constrain scalar, pseudoscalar, and tensor new physics effective couplings, based on the standard model effective field theory at low energies. We have performed a global analysis for the different effective couplings. We also present the different individual constraints for each effective parameter (scalar, pseudoscalar, and tensor). Being a global analysis, we show robust results for the restrictions on the different GNI parameters and improve some of these bounds.
