Two-Loop Effective Potential Calculation of the Lightest CP-Even Higgs-Boson Mass in the MSSM
Ren-Jie Zhang
Abstract
We calculate a two-loop effective potential to the order of O(λt2αs) in the MSSM. We then study the corresponding two-loop corrections to the CP-even Higgs-boson mass for arbitrary βand left-right top-squark mixings. We find that the lightest Higgs-boson mass is changed by at most a few GeV. We also show the improved scale dependence and compare to previous two-loop analyses.
