MSSM lightest CP-even Higgs boson mass to Script O(αsαt): the effective potential approach

摘要: Starting with the two-loop effective potential of MSSM, and assuming a supersymmetric scale well above MZ, we derive simple analytical approximation for lightest CP-even Higgs boson mass including resummation higher order logarithmic terms via RG-improvement finite non-logarithmic up to (αsαt). This formula describes most relevant radiative corrections MSSM mass, in particular, those associated non-zero top-squark mixing.
