“…Finally, in 2019 the O(α t α 2 s ) corrections to the lighter Higgs mass in the limit of vanishing external momentum were computed for arbitrary values of the SUSY masses in Refs. [75,76]. The three-loop integrals that do not have analytical solutions were computed numerically with the methods of Ref.…”

Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model, where they play a crucial role in constraining the parameter space. The discovery of a Higgs boson and the remarkably precise measurement of its mass at the LHC have spurred new efforts aimed at improving the accuracy of the theoretical predictions for the Higgs masses in supersymmetric models. The “Precision SUSY Higgs Mass Calculation Initiative” (KUTS) was launched in 2014 to provide a forum for discussions between the different groups involved in these efforts. This report aims to present a comprehensive overview of the current status of Higgs-mass calculations in supersymmetric models, to document the many advances that were achieved in recent years and were discussed during the KUTS meetings, and to outline the prospects for future improvements in these calculations.

“…A fixed-order computation is thus recommended for low values of M SUSY not separated too much from M t . For high SUSY energy scales, a resummation of the large logarithms with the help of the renormalization group techniques is required as was discussed in [46]. Once the resummation is performed, the dependence on M SUSY can be evaluated up to superhigh energy scales of the order of the SUSY grand unified theory (GUT) energy.…”

In this paper, we review the status of the computations of the perturbative quantum corrections to the Higgs boson mass in the Standard Model and in its supersymmetric extensions. In particular, supersymmetric theories require a very accurate computation of the Higgs boson mass, which includes corrections even up to the three-loop level, since their predictions are limited by theoretical uncertainties. A discussion about these uncertainties in the context of the Minimal and Next To Minimal Supersymmetric Standard Model is included.

“…There are different approaches to calculate the Higgs boson mass in supersymmetric models, which can be roughly classified into fixed-order , 1 EFT [40][41][42][43][44][45][46][47][48][49][50][51], and hybrid [52][53][54][55][56][57][58][59][60][61] approaches, which combine the virtues of the former two. Fixed-order approaches truncate the perturbation series at a certain order in loops and couplings, neglecting in particular large logarithmic corrections arising at higher orders.…”

We present an improved calculation of the light CP-even Higgs boson pole mass in the MSSM based on the FlexibleEFTHiggs hybrid method. The calculation resums large logarithms to all orders and includes power-suppressed terms at fixed order. It uses stateof-the-art 2-and 3-loop matching of the quartic Higgs coupling and renormalization group running up to 4-loop, resulting in a resummation of large logarithmic corrections up to N 3 LL level. A conceptually novel ingredient is the expansion of the matching conditions in terms of high-scale MSSM parameters instead of SM parameters. In this way leading QCD-enhanced terms in the stop-mixing parameter are effectively resummed, leading to an improved numerical convergence of the perturbative expansion. Furthermore, the avoidance of double counting of loop corrections is more transparent than in other approaches and more independent of the high-scale model. We present numerical results and a detailed discussion of theoretical uncertainties for standard benchmark scenarios.
