Multi-Higgs boson production in the Standard Model and beyond

چکیده

We present a calculation of the loop-induced processes gg → HH and gg → HHH , and investigate the observability of multi-Higgs boson production at the CERN Large Hadron Collider (LHC) in the Standard Model (SM) and beyond. While the SM cross sections are too small to allow observation at the LHC, we demonstrate that physics beyond the SM can lead to amplified, observable cross sections. Furthermore, the applicability of the heavy top quark approximation in twoand three-Higgs boson production is investigated. We conclude that multi-Higgs boson production at the SuperLHC is an interesting probe of Higgs sectors beyond the SM and warrants further study.

Singlet scalar dark matter in noncommutative space

In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered,  but our information about  the nature of dark matter is still limited. There are such particle candidates as  scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...

قواعد فاینمن در مدل استاندارد تعمیم یافته

 We consider the Lorentz violating extension of the standard model introduced by D. Colladay and V. A. Kostelecky. In this framework, we obtain all Feynman rules for the electroweak part of the standard model extension (SME), for the first time. Among the new obtained interactions one finds new vertices for the Higgs boson that is interesting in the phenomenology of the Higgs particle.

Multiple Higgs Production and Measurement of Higgs Trilinear Couplings in the MSSM

An elementary Higgs boson, which is the remnant of the spontaneous symmetry breaking mechanism in the Standard Model, remains one of the most elusive particles. If a Higgs boson candidate is found at future accelerators, it becomes necessary to determine its properties, beyond the mass, production cross section and decay rates. The other crucial properties relate to the self-couplings of the Hi...

Tevatron searches for Higgs bosons beyond the standard model

Theoretical frameworks beyond the standard model predict a rich Higgs sector with multiple charged and neutral Higgs bosons. Both the CDF II and DØ experiments at the Tevatron have analyzed 1 fb−1 of pp̄ collisions at √ s = 1.96TeV in search of Higgs boson production. A complete suite of results on searches for neutral, charged, and fermiophobic Higgs bosons limit the allowed production rates an...

Effects of the littlest Higgs model with T-parity on Higgs boson production at high energy e+e− colliders

The Higgs boson production processes e+e− → ZH, e+e− → ν̄eνeH, and e+e− → tt̄H are very important for studying Higgs boson properties and further testing new physics beyond the standard model(SM) in the high energy linear e+e− collider(ILC). We estimate the contributions of the littlest Higgs model with Tparity(LHT model) to these processes and find that the LHT model can generate significantly c...
