Abstract. The status of the evaluation of the MSSM Higgs sector is reviewed. The phenomenological impact of recently obtained corrections is discussed. In particular it is shown that the upper bound on mh within the MSSM is shifted upwards. Consequently, lower limits on $\tan\beta$ obtained by confronting the upper bound as function of $\tan\beta$ with the lower bound on mh from Higgs searches are significantly weakened. Furthermore, th e region in the MA-$\tan\beta$-plane where the coupling of the lightest Higgs boson to down-type fermions is suppressed is modified. The presently not calculated higher-order corrections to the Higgs-boson mass matrix are estimated to shift the mass of the lightest Higgs boson by up to 3 GeV.

- Fully covering the MSSM Higgs sector at the LHC (2015, background): “If one allows for an uncertainty of a say 3 GeV in the determination of the h mass in the MSSM, from unknown higher order contributions for instance [41–44], the situation is acceptable if the h mass is confined in the range 122 GeV <∼Mh<∼ 128 GeV.”
