Precise Higgs mass calculations in (non-)minimal supersymmetry at both high and low scales

Understand

We present FlexibleEFTHiggs, a method for calculating the SM-like Higgs pole mass in SUSY (and even non-SUSY) models, which combines an effective field theory approach with a diagrammatic calculation.

• It thus achieves an all order resummation of leading logarithms together with the inclusion of all non-logarithmic 1-loop contributions.
• We implement this method into FlexibleSUSY and study its properties in the MSSM, NMSSM, E6SSM and MRSSM.
• In the MSSM, it correctly interpolates between the known results of effective field theory calculations in the literature for a high SUSY scale and fixed-order calculations in the full theory for a sub-TeV SUSY scale.
