“…Therefore, for simplicity we will neglect holomorphic mass terms for S and T adjoint scalars, as well as their trilinear couplings among themselves and to the Higgs bosons since their presence does not influence our results significantly (however, see also [34]). Thus the soft-breaking scalar mass terms read…”

R-symmetry is a fundamental symmetry which can solve the SUSY flavor problem and relax the search limits on SUSY masses. Here we provide a complete next-toleading order computation and discussion of the lightest Higgs boson mass, the W boson mass and muon decay in the minimal R-symmetric SUSY model (MRSSM). This model contains non-MSSM particles including a Higgs triplet, Dirac gauginos and higgsinos, and leads to significant new tree-level and one-loop contributions to these observables. We show that the model can accommodate the measured values of the observables for interesting regions of parameter space with stop masses of order 1 TeV in spite of the absence of stop mixing. We characterize these regions and provide typical benchmark points, which are also checked against further experimental constraints. A detailed exposition of the model, its mass matrices and its Feynman rules relevant for computations in this paper is also provided.

“…This Higgs sector is quite complex, and variations of the Higgs potential in R-symmetric models have been recently been studied [19,21]. Our low energy superpotential will contain the Dirac-gaugino masses for the elctroweak sector as well electroweak adjoints coupling directly to the Higgs [10].…”

In this work we calculate important one loop SUSY-breaking parameters in models with Dirac gauginos, which are implied by the existence of heavy messenger fields. We find that these SUSY-breaking effects are all related by a small number of parameters, thus the general theory is tightly predictive. In order to make the most accurate analyses of one loop effects, we introduce calculations using an expansion in SUSY breaking messenger mass, rather than relying on postulating the forms of effective operators. We use this expansion to calculate one loop contributions to gaugino masses, non-holomorphic SM adjoint masses, new A-like and B-like terms, and linear terms. We also test the Higgs potential in such models, and calculate one loop contributions to the Higgs mass in certain limits of R-symmetric models, finding a very large contribution in many regions of the / µMSSM, where Higgs fields couple to standard model adjoint fields.

“…Since the discovery of a Higgs boson by the ATLAS and CMS experiments at the LHC it became of interest if this model can accommodate it. First answer to this question was given in [2], followed by calculation of complete one-loop corrections to Higgs and W boson masses [3] and two-loop corrections in the effective potential approximation and gauge-less limit [4]. In this note we briefly review results presented in [3].…”
