چکیده

The Higgs-boson production in association with a W-boson pair at e+e− linear colliders is one of the important processes in probing the coupling between Higgsboson and vector gauge bosons and discovering the signature of new physics. We describe the impact of the complete electroweak(EW) radiative corrections of O(αew) to this process in the standard model(SM) at the International Linear Collider(ILC), and investigate the dependence of the lowest-order(LO) and EW next-to-leading order(NLO) corrected cross sections on colliding energy √ s and Higg-boson mass. The LO and NLO EW corrected distributions of the invariant mass of W-boson pair and the transverse momenta of final W and Higgs-boson are presented. Our numerical results show that the relative EW radiative correction(δew) varies from −19.4% to 0.2% when mH = 120 GeV and √ s goes up from 300 GeV to 1.2 TeV .

Higgs Decay to Photons at Two Loops *

The standard model (SM) predicts the existence of one scalar particle, the Higgs boson (H). The Higgs boson is the only particle of the SM which has not been found until now. Electroweak precision data mainly collected at CERN LEP and SLAC SLC in combination with the direct top-quark mass measurement at the Tevatron would favour a light Higgs boson with a mass below about 200 GeV at the 95% con...

Impact of tau polarization on the study of the MSSM charged Higgs bosons in top quark decays at the ILC

The process of top quark pair production at the ILC with subsequent decays of one of the top quarks to a charged Higgs boson and b-quark is considered. The charged Higgs decays to tau leptons whose polarization is the opposite to those coming from W bosons. This difference is reflected in the energy distributions of the tau decay products in the top quark rest frame, which can be reconstructed ...

SM Precision Constraints at the LHC/ILC

The prospects for electroweak precision physics at the LHC and the ILC are reviewed. This includes projections for measurements of the effective Z pole weak mixing angle, sin2 θ eff. W , as well as top quark, W boson, and Higgs scalar properties. The upcoming years may also see very precise determinations of sin2 θ eff. W from lower energies.

The littlest Higgs model and Higgs boson associated production with top quark pair at high energy linear e+e− collider

In the parameter space allowed by the electroweak precision measurement data, we consider the contributions of the new particles predicted by the littlest Higgs(LH) model to the Higgs boson associated production with top quark pair in the future high energy linear ee collider(ILC). We find that the contributions mainly come from the new gauge bosons ZH and BH . For reasonable values of the free...
