- W1811281514 abstract "We revisit the issue of considering stochasticity of Grassmannian coordinates in $N=1$ superspace, which was analyzed previously by Kobakhidze et al. In this stochastic supersymmetry (SUSY) framework, the soft SUSY breaking terms of the minimal supersymmetric Standard Model (MSSM) such as the bilinear Higgs mixing, trilinear coupling, as well as the gaugino mass parameters are all proportional to a single mass parameter $ensuremath{xi}$, a measure of supersymmetry breaking arising out of stochasticity. While a nonvanishing trilinear coupling at the high scale is a natural outcome of the framework, a favorable signature for obtaining the lighter Higgs boson mass ${m}_{h}$ at 125 GeV, the model produces tachyonic sleptons or staus turning to be too light. The previous analyses took $ensuremath{Lambda}$, the scale at which input parameters are given, to be larger than the gauge coupling unification scale ${M}_{G}$ in order to generate acceptable scalar masses radiatively at the electroweak scale. Still, this was inadequate for obtaining ${m}_{h}$ at 125 GeV. We find that Higgs at 125 GeV is highly achievable, provided we are ready to accommodate a nonvanishing scalar mass soft SUSY breaking term similar to what is done in minimal anomaly mediated SUSY breaking (AMSB) in contrast to a pure AMSB setup. Thus, the model can easily accommodate Higgs data, LHC limits of squark masses, WMAP data for dark matter relic density, flavor physics constraints, and XENON100 data. In contrast to the previous analyses, we consider $ensuremath{Lambda}={M}_{G}$, thus avoiding any ambiguities of a post-grand unified theory physics. The idea of stochastic superspace can easily be generalized to various scenarios beyond the MSSM." @default.
