Prediction of the dark fermion mass using multicritical-point principle

This paper proposes a method to determine the effective potential using the multicritical-point principle (MPP) under the additional scalar field. The MPP is applied to the model in which a singlet dark fermion and a singlet real scalar field are added to the Standard Model (SM) to predict the dark fermion mass. As a result, the dark fermion mass is predicted to be about 901–972 GeV.
