Higgs boson mass corrections in the μνSSM with explicit CP violation

Compared to the minimal supersymmetric standard model (MSSM), [Formula: see text] from [Formula: see text] Supersymmetric Standard Model ([Formula: see text]SSM) introduces three singlet right-handed neutrino superfields, which lead to the mixing of the Higgs doublets with the sneutrinos. This mixing affects the Standard Model (SM)-like Higgs boson mass. In this work, we separately give the mixing of the CP-even and CP-odd neutral scalar mass matrices with the explicit CP violation, and analyze how the phases impact the SM-like Higgs boson mass and the signal strengths. At the same time, we give the radiative corrections for the Higgs boson mass with effective potential methods.
