Effects of charged Higgs boson and QCD corrections in B̄ →
نویسندگان
چکیده
We study effects of charged Higgs boson exchange in B̄ → Dτν̄τ . The Yukawa couplings of Model II of two-Higgs-doublet model, which has the same Yukawa couplings as MSSM, is considered. We evaluate the decay rate including next-toleading QCD corrections and estimate uncertainties in the theoretical calculation. Our analysis will contribute to probe an extended Higgs sector at B factory experiments. Talk given by T.

QCD Corrections to B̄ → X d , s νν̄ , B̄ d , s → l + l − , K → πνν̄ and K L → μ + μ − in the MSSM
We compute for the first time QCD corrections to the rare decays B̄ → Xd,sνν̄, B̄d,s → l+l−, K → πνν̄ and KL → μ+μ−, where l = e or μ, in the context of a supersymmetric extension of the Standard Model (SM) with minimal flavour violation and new operators, in addition to those present in the SM. Assuming that the gluino is heavy, we consider an effective theory which consists of charged and neutral...
متن کاملO(αs) Corrections to bb̄ → W±H∓ at the CERN Large Hadron Collider
Institut für Theoretische Physik, Universität Karlsruhe D-76128 Karlsruhe, Germany The O(αs) corrections to the cross section for bb̄ → W±H∓ at the LHC are calculated in the minimal supersymmetric standard model (MSSM) in the MS and OS (on-mass-shell) renormalization schemes. The results in two schemes are in good agreement. In the MS scheme, the QCD corrections are negative and within −14% ∼ −2...
متن کاملQCD corrections to charged triple vector boson production with leptonic decay
We compute the O(αs) QCD corrections to charged triple vector boson production at a hadron collider, i.e. the processes pp → ZZW +X and pp → WWW +X. Intermediate Higgs boson exchange effects, spin correlations from leptonic vector boson decays, and off-shell contributions are all taken into account. Results are implemented in a fully flexible Monte Carlo program that allows for an easy customiz...
متن کاملRenormalization-Group-Improved Effective Potential for the MSSM Higgs Sector with Explicit CP Violation
We perform a systematic study of the one-loop renormalization-group-improved effective potential of the minimal supersymmetric extension of the Standard Model (MSSM), including CP violation induced radiatively by soft trilinear interactions related to squarks of the third generation. We calculate the charged and neutral Higgs-boson masses and couplings, including the two-loop logarithmic correc...
