Two-Loop Correction to the Higgs Boson Mass in the MRSSM

Abstract EN

We present the impact of two-loop corrections on the mass of the lightest Higgs boson in the minimal R-symmetric supersymmetric standard model (MRSSM).

These shift the Higgs boson mass up by typically 5 GeV or more.

The dominant corrections arise from strong interactions, and from the gluon and its N=2 superpartners, the sgluon and Dirac gluino, and these corrections further increase with large Dirac gluino mass.

The two-loop contributions governed purely by Yukawa couplings and the MRSSM λ, Λ parameters are smaller.

We also update our earlier analysis which showed that the MRSSM can accommodate the measured Higgs and W boson masses.

Including the two-loop corrections increases the parameter space where the theory prediction agrees with the measurement.
