چکیده
Abstract We extend the already existing two-loop calculation of effective bottom-Yukawa coupling in MSSM. In addition to resummation dominant corrections for large values tg $$\beta $$ β , we include subleading terms related trilinear Higgs $$A_b$$ xmlns:mml="http://www.w3.org/1998/Math/MathML">Ab and contributions induced by electroweak gauge couplings. This has been extended NNLO MSSM strange-Yukawa coupling. Our analysis leads residual theoretical uncertainties Yukawa couplings at per-cent level.

Higgs-dependent Yukawa couplings
We consider the possibility that the Yukawa couplings depend on the Higgs field, with the motivation of generating the fermion mass hierarchy through appropriate powers of the Higgs vacuum expectation value. This leads to drastic modifications of the Higgs branching ratios, new Higgs contributions to various flavor-violating processes, and observable rates for the top quark decay t → hc. The un...
متن کاملMeasuring the Higgs Boson Yukawa Couplings at an NLC
The search for the Higgs boson is one of the primary objectives of present and future colliders. Once the Higgs boson has been discovered, it will be important to measure its couplings to fermions and to gauge bosons. These couplings are completely determined in the Standard Model and the process ee ! tth provides a direct mechanism for measuring the tth Yukawa coupling. Since this coupling can...
متن کاملYukawa coupling quantum corrections to the self couplings of the lightest MSSM Higgs boson
A detailed analysis of the top-quark/squark quantum corrections to the lightest CP-even Higgs boson (h) self-couplings is presented in the MSSM. By considering the leading oneloop Yukawa-coupling contributions of O(mt ), we discuss the decoupling behaviour of these corrections when the top-squarks are heavy compared to the electroweak scale. As shown analytically and numerically, the large corr...
متن کاملMeasuring the Higgs Yukawa couplings at photon colliders
The idea of fermion mass generation through Yukawa couplings between Higgs bosons and fermions may be tested by their associate production at the future linear colliders ( LC ). We examine the possibility of measuring these couplings at photon colliders that can be realized by the laser back-scattering technique at the LC. We study specifically the case of the minimal supersymmeric standard mod...
متن کاملMeasuring Trilinear Higgs Couplings in the MSSM
Trilinear couplings of the neutral CP -even Higgs bosons in the Minimal Supersymmetric Standard Model (MSSM) can be measured through the multiple production of the lightest CP -even Higgs boson (h) at high-energy ee colliders. This includes the production of the heavier CP -even Higgs boson (H) via ee → ZH, in association with the CP -odd Higgs boson (A) in ee → AH, or via ee → νeν̄eH, with H su...
