Contribution of Neutralino and Chargino to Diagonal Form Factor of Majorana Neutrino in the Minimal Supersymmetric Standard Model

Abstract

In this study, we have calculated the diagonal form factor and charge radius of Majorana neutrinos in the Minimal Supersymmetry Standard Model (MSSM) using Feynman-'t Hooft gauge and dimensional regularization. From the obtained result of calculations, we have seen that the main contribution come from chargino particles in MSSM and its contribution is very small than SM contribution. It is found that 〈r_ν^2 〉=1,66 .〖10〗^(-32) cm^2 for the charge radius of electron neutrinos which is in good agreement with results obtained from the scattering experiments.
