2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/49699We analyze the impact of the recent Feynman-diagrammatic (FD) two-loop results for the mass of the lightest CP-even Higgs boson in the MSSM on the theoretical upper bound for mh as a function of tan(beta). The results are compared with previous results obtained by renormalization group (RG) methods. The incorporation of dominant FD two-loop corrections into the decay width Γ(h -> f \bar f) is also discussed.4 pages, 2 figures, presented by G.
