Supersymmetric threshold corrections to the Higgs sector in the minimal supersymmetric model

In the minimal supersymmetric extension of the Standard Model (MSSM), the Higgs self-interactions are related to the SU(2)_L x U(1)_Y gauge couplings. Thus, only two additional inputs are needed in order to completely determine the Higgs sector of the theory. However, these relations acquire radiative corrections when supersymmetry (SUSY) is broken. In this paper, we investigate the phenomenological implications of the corrections due to trilinear Higgs-squark-squark interactions.
