“…These also determine the value of the SM-like Higgs mass at the loop level. Values of the third generation squark masses of about 1 TeV lead to SM-like Higgs masses in the 115-130 GeV range [6]- [15]. Hence, recent hints of a Higgs mass of about 125 GeV are consistent with MSSM predictions [16].…”

“…This has the correct form for the evolution equation for the gauge couplings from the scale M GU T , where 1/g 2 i = 2, to other energies, provided we interpret 15) or, equivalently the right panel in this figure, we see that the LHC has had a pretty significant effect on the expectation of M unif . We clearly see that scales of order 10 8 − 10 15 GeV have become more favored, whereas there is a clear depletion of probability near the weak scale.…”

The LHC has started to constrain supersymmetry-breaking parameters by setting bounds on possible colored particles at the weak scale. Moreover, constraints from Higgs physics, flavor physics, the anomalous magnetic moment of the muon, as well as from searches at LEP and the Tevatron have set additional bounds on these parameters. Renormalization Group Invariants (RGIs) provide a very useful way of representing the allowed parameter space by making direct connection with the values of these parameters at the messenger scale. Using a general approach, based on the pMSSM parametrization of the soft supersymmetry-breaking parameters, we analyze the current experimental constraints to determine the probability distributions for the RGIs. As examples of their application, we use these distributions to analyze the question of Gaugino Mass Unification and to probabilistically determine the parameters of General and Minimal Gauge Mediation with arbitrary Higgs mass parameters at the Messenger Scale. * http://theory.fnal.gov 0

“…The calculations make use of the generic results of Refs. [56][57][58][59][60] and the only approximations used in the SARAH implementation of the two-loop calculations are (1) the gaugeless limit, i.e. setting g 1 = g 2 = 0, and (2) neglecting the momentum dependence, i.e.…”

For a long time, the minimal supersymmetric standard model (MSSM) with light masses for the supersymmetric states was considered as the most natural extension of the Standard Model of particle physics. Consequently, a valid approximation was to match the MSSM to the precision measurement directly at the electroweak scale. This approach was also utilized by all dedicated spectrum generators for the MSSM. However, the higher the supersymmetric (SUSY) scale is, the bigger the uncertainties which are introduced by this matching. We point out important consequences of a two-scale matching, where the running parameters within the SM are calculated at M Z and evaluated up to the SUSY scale, where they are matched to the full model. We show the impact on gauge coupling unification as well as the SUSY mass spectrum. Also the Higgs mass prediction for large supersymmetric masses has been improved by performing the calculation within an effective SM. The approach presented here is now also available in the spectrum generator SPheno. Moreover, also SARAH was extended accordingly and gives the possibility to study these effects now in many different supersymmetric models.

“…[22,90,91], arises either in the MSSM beyond the gaugeless limit, or in theories beyond the MSSM even in the gaugeless limit, in that the DR mass-squred of Goldstone bosons may be negative (and the Goldstone bosons themselves have non-zero couplings to the Higgs). The full on-shell mass of course being zero, the DR Goldstone boson mass parameter is thus of the same order as loop corrections and is small.…”

We discuss the automatised calculation of the Higgs mass in renormalisable supersymmetric models with complex parameters at the two-loop level. Our setup is based on the public codes SARAH and SPheno, which can now compute the two-loop corrections to masses of all neutral scalars in such theories. The generic ansatz for these calculations and the handling of the 'Goldstone Boson catastrophe' is described. It is shown that we find perfect agreement with other existing two-loop calculations performed in the DR scheme. We also use the functionality to derive results for the MSSM and NMSSM not available before: the Higgs mass in the constrained version of the complex MSSM and the impact of CP phases in the two-loop corrections beyond O(α s α t ) for the scale-invariant NMSSM are briefly analysed.
