Abstract
Abstract
We analyze the appearance of the trilinear squark-Higgs couplings xq in Green functions in the Higgs sector of the MSSM and in threshold corrections to the SM. The results are constraints on maximal powers of xq in QCD-related loop corrections. In practice these often imply all-order resummations of leading or subleading xq contributions in SM-parametrized expressions. We present a variety of all-order resummation relations for ∆λ which include such xq-enhanced terms and different orders in Yukawa and gauge couplings. We contrast which terms cannot be resummed.
