“…[57] have been used. For large values of tan β, the pseudoscalar Higgs boson contribution gives a sizeable deviation from the Standard Model expectation so that when non-minimal flavour violation in the squark sector is allowed, this observable mainly restricts left-right mixing parameters [58].…”

We present an extensive study of non-minimal flavour violation in the squark sector in the framework of the Minimal Supersymmetric Standard Model. We investigate the effects of multiple non-vanishing flavour-violating elements in the squark mass matrices by means of a Markov Chain Monte Carlo scanning technique and identify parameter combinations that are favoured by both current data and theoretical constraints. We then detail the resulting distributions of the flavour-conserving and flavour-violating model parameters. Based on this analysis, we propose a set of benchmark scenarios relevant for future studies of non-minimal flavour violation in the Minimal Supersymmetric Standard Model.

In order to accommodate the observed Higgs boson mass in the CMSSM, the stops must either be very heavy or the mixing in the stop sector must be very large. Lower stop masses, possibly more accessible at the LHC, still give the correct Higgs mass only if the trilinear stop mixing parameter |A t | is in the multi-TeV range. Recently it has been shown that such large stop mixing leads to an unstable electroweak vacuum which spontaneously breaks charge or color. In this work we therefore go beyond the CMSSM and investigate the effects of including baryon number violating operators λ ŪDD on the stop and Higgs sectors. We find that for λ O(0.3) light stop masses as low as 220 GeV are consistent with the observed Higgs mass as well as flavour constraints while allowing for a stable vacuum. The light stop in this scenario is often the lightest supersymmetric particle. We furthermore discuss the importance of the one-loop corrections involving R-parity violating couplings for a valid prediction of the light stop masses.

“…Having determined the low-energy constraints, we propose constrained boundary conditions at the GUT scale, thus defining a new constrained minimal Dirac gaugino supersymmetric Standard Model in section V. We implement this model in the spectrum generator generator SARAH [55][56][57][58][59][60], details of which we provide in appendix C, produce and modify the subsequent SPheno [61,62] code, and use it to perform some exploratory scans of the parameter space. Our main results are given in the form of "generic predictions" in section V C. We also provide simplified renormalisation group equations for the model in appendix D. 3 , which is a measure of the relative deviation from "unification" which should be close to zero and certainly less than unity for good agreement.…”

Constrained minimal Dirac gaugino supersymmetric standard model

We examine the possibilities for constructing models with Dirac gaugino masses and unification of gauge couplings. We identify one promising model, and discuss to what extent it can have a "natural SUSY" spectrum. We then determine the low-energy constraints upon it, and propose a constrained set of boundary conditions at the unification scale. We describe the implementation of these boundary conditions in the spectrum-generator generator SARAH and we perform a first exploration of the parameter space, specifically searching for points where the spectrum is relatively light. It is shown that the pattern of the masses of SUSY states is very different compared to any expectations from the constrained MSSM.
