Precise prediction for the Higgs-Boson Masses in the $\mu\nu$SSM with three right-handed neutrino superfields

Understand

The $\mu\nu$SSM is a simple supersymmetric extension of the Standard Model (SM) capable of describing neutrino physics in agreement with experiments.

• We perform the complete one-loop renormalization of the neutral scalar sector of the $\mu\nu$SSM with three generation of right-handed neutrinos in a mixed on-shell/$\overline{\mathrm{DR}}$ scheme.
• We calculate the full one-loop corrections to the neutral scalar masses of the $\mu\nu$SSM.
• The one-loop contributions are supplemented by available MSSM higher-order corrections.
