Starting with the two-loop effective potential of the MSSM, and assuming asupersymmetric scale well above $M_Z$, we derive a simple analyticalapproximation for the lightest CP-even Higgs boson mass including resummationof higher order logarithmic terms via RG-improvement and finite non-logarithmicterms up to ${\cal O}(\alpha_s\alpha_t)$. This formula describes the mostrelevant radiative corrections to the MSSM Higgs boson mass, in particular,those associated with non-zero top-squark mixing.Comment: 14 pages, to match the published versio
