Findings

Dark fermion mass predicted to be 901-972 GeV

Method demonstrates the use of MPP in dark matter models

Provides a specific mass range for dark fermion

Abstract

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.
