TL;DR

This paper investigates one-loop corrections to neutrino masses within the BLMSSM, a supersymmetric extension of the standard model with gauged baryon and lepton numbers, highlighting their significance for understanding neutrino properties.

Contribution

It provides a detailed analysis of one-loop corrections to neutrino masses in BLMSSM using the mass insertion approximation, expanding the understanding of neutrino mass generation beyond tree level.

Findings

One-loop corrections significantly affect neutrino mass predictions.

Parameter space constraints are identified for BLMSSM.

Results support BLMSSM as a viable framework for neutrino physics.

Abstract

The neutrino masses and mixings are studied in the model which is the supersymmetric extension of the standard model with local gauged baryon and lepton numbers(BLMSSM). At tree level the neutrinos can obtain tiny masses through the See-Saw mechanism in the BLMSSM. The one-loop corrections to the neutrino masses and mixings are important, and they are studied in this work with the mass insertion approximation. We study the numerical results and discuss the allowed parameter space of BLMSSM. It can contribute to study the neutrino masses and to explore the new physics beyond the standard model(SM).
