Two-loop correction to the Higgs boson mass in the MRSSM

Understand

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, 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 $\lambda,\Lambda$ parameters are smaller.
