Precise Calculations for the Neutral Higgs-Boson Masses in the MSSM
S. Heinemeyer, W. Hollik, G. Weiglein
Abstract
We review the comparison of the results for the neutral CP-even Higgs-boson masses recently obtained within the Feynman-diagrammatic approach with the previous results based on the renormalization group approach. We show that the results differ by new genuine two-loop contributions present in the Feynman-diagrammatic calculation. The numerical effect of these terms on the result for mh is briefly discussed.
