Non-decoupling Effects of Heavy Particles in Triple Gauge Boson Vertices
نویسنده
چکیده
Non-decoupling effects of heavy particles present in beyond-the-standard models are studied for the triple gauge boson vertices γWW and ZWW. We show from a general argument that the non-decoupling effects are described by four independent parameters, in comparison with the three parameters S, T and U in the oblique corrections. These four parameters of the effective triple gauge boson vertices are computed in two beyond-the-standard models. We also study the relation of the four parameters to the S, T , U parameters, relying on an operator analysis. † Present address: Shikata-cho 849, Kakogawa, Hyogo 675-03, Japan

The Higgs Sector of the Mssm in the Decoupling Limit
We study the heavy Higgs sector of the MSSM composed of the H±, H and A particles in the so-called decoupling limit where mA0 mZ . By integrating out these heavy Higgs particles to one-loop, we compute the effective action for the electroweak gauge bosons and find out that, in the decoupling limit, all the heavy Higgs effects can be absorbed into redefinitions of the Standard Model electroweak ...

Supersymmetry implies that the trilinear couplings between gauge bosons and gaug-inos are equal to all orders. However if SUSY is broken and some of the superpartners have large SUSY breaking masses then they can induce non-decoupling deviations in this relation through radiative corrections. In this work we show that the deviation in the ratiõ g w ˜ χ˜γ g γww from unity can be around 2.3% (3.3...

متن کاملNLO QCD Corrections and Triple Gauge Boson Vertices at the NLC
We study NLO QCD corrections as relevant to hadronic W decay in W pair production at a future 500 GeV ee linac, with particular emphasis on the determination of triple gauge boson vertices. We find that hard gluon bremstrahlung may mimic signatures of anomalous triple gauge boson vertices in certain distributions. The size of these effects can strongly depend on the polarisation of the initial ...
متن کاملTwo-loop large Higgs mass corrections to electroweak gauge boson quartic couplings
The two-loop corrections to the electroweak gauge boson quartic couplings, growing quadratically with the Higgs boson mass, are calculated in the Standard Model in the limit of large Higgs mass. The corrections to WWWW , WWZZ and ZZZZ four-vertices are found to be an order of magnitude larger than the two-loop m2H corrections to light fermion and triple gauge boson vertices. For a heavy Higgs b...
