The flavor transition process $b\rightarrow s\gamma$ in the $U(1)_X$SSM with the mass insertion approximation
arxiv(2022)
Abstract
People extend the MSSM with the local gauge group $U(1)_X$ to obtain the $U(1)_X$SSM. In the framework of the $U(1)_X$SSM, we study the flavor transition process $b\rightarrow{s\gamma}$ with the mass insertion approximation (MIA). By using the MIA method with some assumptions on parameters, we find the parameters that directly affect the analytical result of the flavor transition process $b\rightarrow{s\gamma}$. According to the influences of different sensitive parameters, we can obtain reasonable results to better fit the experimental data.
