The light MSSM Higgs mass: merging fixed order and resummation at three loopRobert V. Harlander, •Jonas Klappert, Lars-Thorben Moos, Daniel Ochoa, and Alexander Voigt — RWTH Aachen University

Results for the light Higgs mass in the MSSM up to three-loop order including the corresponding uncertainties are discussed. Since experimental exclusions push the threshold of masses of potential SUSY partner particles to the TeV scale, it is necessary to resum terms which are enhanced by logarithms of the SUSY scale. In this talk, we present a combined technique based on a diagrammatic fixed-order and an EFT approach to reduce the origin of the individual uncertainties and to obtain a reliable result for the light Higgs mass. All results are publicly available in the Himalaya library.
