Meeting Higgs and Electroweak Precision Observables with R-symmetric SUSY

Abstract

The Standard Model of Particle Physics, despite its success at describing most of the available experimental data, cannot be the fundamental theory of Nature. Phenomena such as the existence of dark matter or the anomalous magnetic moment of the muon call for its extension. These questions could be addressed by supersymmetry, and for many the Minimal Supersymmetric Standard Model (MSSM) is the theory of choice. But despite a very successful Run 1, no sign of supersymmetry was found at the LHC. Therefore, one has to consider the possibility that low scale SUSY, if it is realized in Nature, might not be realized in the minimal way. This generated a lot of interest in both simple extensions of the MSSM, like the NMSSM, and more involved but arguably theoretically better motivated, like for example the Minimal R-symmetric Supersymmetric Standard Model (MRSSM). The latter one, proposed in Ref. [1] in the context of ameliorating the flavor problem of the MSSM, looks also very promising from the point of view of Higgs physics. The Higgs sector of this model was worked out in Refs. [2, 3]. This included calculations of full one-loop and partial two-loop corrections to the mass spectrum. In this work, we summarize briefly results of the two-loop analysis.
