Transition magnetic moment of Majorana neutrinos in the triplets next-to-minimal MSSM

TL;DR

This paper investigates the transition magnetic moments of Majorana neutrinos within the TNMSSM, considering one-loop corrections and experimental constraints, and compares the solar neutrino magnetic moment with XENONnT limits.

Contribution

It provides a detailed calculation of Majorana neutrino transition magnetic moments in the TNMSSM, incorporating one-loop corrections and experimental data constraints.

Findings

Transition magnetic moments are computed for normal and inverse hierarchy spectra.

The solar neutrino magnetic moment is estimated and compared with experimental limits.

Results suggest potential observability within current experimental bounds.

Abstract

The TNMSSM is an attractive extension of the Standard Model. It combines the advantages of the NMSSM and the TMSSM to give three tiny Majorana neutrinos masses via a type I+II seesaw mechanism. With the on-shell renormalization scheme, we consider the neutrino masses up to one loop approximation. Applying the effective Lagrangian method, we study the transition magnetic moments of Majorana neutrinos and consider the normal hierarchy (NH) and inverse hierarchy (IH) neutrino mass spectra within the constraints of experimental data on neutrino oscillations. The solar neutrino transition magnetic moment is further deduced, and compared with the XENONnT experiment limit.
