Complete Two-loop Dominant Corrections to the Mass of the Lightest CP-even Higgs Boson in the Minimal Supersymmetric Standard Model

Jose Ramon Espinosa, Ren-Jie Zhang

Using an effective potential approach, we compute two-loop radiative corrections to the MSSM lightest $\mathcal{C}\mathcal{P}$-even Higgs boson mass $M_{h^0}$ to $\mathcal{O}({\alpha }_t^2)$ for arbitrary…
