MSSM: cornered and correlated

Open Access


Inspired by the latest results of ATLAS and CMS on the search for the standard model (SM) Higgs scalar, we discuss in this article the correlations between Higgs-boson properties, low-energy observables, such as BX sγ, B sμ + μ , and (g − 2)μ, and the dark matter (DM) relic density. We focus on the corners of the MSSM parameter space where the pph → γγ signal is enhanced due to the presence of a light stau state. In this region tan β, M A , A t, and μ take large values, and we find striking correlations between many of the considered observables. In particular, the BX sγ branching fraction is enhanced, while the B sμ + μ rate tends to be below the SM expectation. In contrast, the Higgs-boson couplings show good overall agreement with the preliminary experimental determinations, the DM abundance is consistent with observation, and the discrepancy in (g − 2) μ is reduced. The predicted deviations and found correlations could be tested in the near future and hence may become very valuable as guidelines and consistency checks.
