چکیده
We consider the production of a Higgs boson in association with two electroweak vector bosons at hadron colliders. In particular, we examine $\gamma\gamma H$, $\gamma ZH$, $ZZH$, and $W^{+}W^{-}H$ LHC (14 TeV), HE-LHC (27 FCC-hh (100 TeV) Our main focus is to estimate gluon-gluon ($gg$) channel ($gg \to VV^\prime H$) contributions $pp H~(V,V^\prime=\gamma,Z,W)$ compare them corresponding arising from quark-quark ($qq$) channel. Technically, leading order $gg$ contribution H$ cross section an NNLO correction $\alpha_s$. processes under consideration, find that channel, has largest section. However, relative more important for ZZH$ production. At FCC-hh, $gg comparable NLO QCD $qq ZZH$. also compute sections when $W$ $Z$-bosons are polarized. contributes significantly longitudinally By examining such events, one can increase fraction these processes. Further, have studied beyond-the-standard-model effects $\kappa$-framework. $ZZH$ $WWH$ very mild dependence on $\kappa_\lambda$, but strong $\kappa_t$ $\kappa_V$. The $qq$ mainly depend Dependence $\kappa_V$ stronger than contribution. Therefore focusing events polarized $Z$-bosons, help us measure this parameter.

Higgs – Boson Production at Hadron Colliders with Explicit CP Violation
Gluon fusion is the main production mechanism for Higgs bosons with masses up to several hundred GeV in pp collisions at the CERN Large Hadron Collider. We investigate the effects of the CP–violating phases on the fusion process including both the sfermion–loop contributions and the one–loop induced CP–violating scalar–pseudoscalar mixing in the minimal supersymmetric standard model. With a uni...
متن کاملTriplet Higgs boson at hadron colliders
The novel feature of a Higgs-triplet representation is a nonzero tree-level coupling of HWZ, which is absent in all Higgs-doublet models. We study the associated production of a singly-charged Higgs boson of the Higgs-triplet representation with a W or Z boson at hadron colliders, followed by the H → WZ decay. We find that the 2l+ 4j final state gives an interesting level of signal with a negli...
متن کاملHiggs Boson Searches at Hadron Colliders
The investigation of the dynamics responsible for electroweak symmetry breaking is one of the prime tasks of experiments at present and future colliders. Experiments at the Tevatron pp Collider and at the CERN Large Hadron Collider (LHC) must be able to discover a Standard Model Higgs boson over the full mass range as well as Higgs bosons in extended models. In this review, the discovery potent...
متن کاملImproved description of charged Higgs boson production at hadron colliders
We present a new method for matching the two twin-processes gb → Ht and gg → Htb in Monte Carlo event generators. The matching is done by defining a double-counting term, which is used to generate events that are subtracted from the sum of the two twin-processes. In this way we get a smooth transition between the collinear region of phase space, which is best described by gb → Ht, and the hard ...
