Charged Higgs Production via bg -> tH(-) at the LHC
نویسنده
چکیده
I present a calculation of QCD radiative corrections to charged Higgs production via the process bg −→ tH. I show that the cross section is dominated by soft-gluon corrections, which are computed through next-to-next-to-leading order. Results for charged Higgs production at the LHC are presented, including the dependence of the cross section on the charged Higgs mass, the top quark mass, the factorization and renormalization scales, and tan β.

Charged Higgs production with a top quark at the LHC
I discuss charged Higgs production via the process bg → tH− at the LHC. I show that the cross section is dominated by soft-gluon corrections and I provide results for its dependence on the charged Higgs mass and on the scale, including higher-order effects. Presented at the DIS 2004 Workshop, Strbske Pleso, Slovakia, 14-18 April, 2004.
متن کاملCharged Higgs Production: Higher-Order Corrections
I present a calculation of higher-order radiative corrections to charged Higgs production in association with a top quark via the process bg → tH −. Results for charged Higgs production at the LHC are presented, including the dependence of the cross section on the charged Higgs mass, the top quark mass, the factorization and renormalization scales, and tan β. I show that the theoretical predict...
متن کاملCharged Higgs Boson Searches at the LHC via Multiple bb̄W± Final States
We review the prospects of the Large Hadron Collider in accessing heavy charged Higgs boson signals in bb̄W± final states, wherein the contributing channels can be H+ → tb̄, hW±, HW± and AW±. In particular, we devise a selection strategy which optimizes their global yield. We consider a 2-Higgs Doublet Model Type-II and we assume as production mode bg→ tH− + c.c., the dominant one over the range ...
متن کاملSearching for heavy charged Higgs bosons in the neutrino–tau decay mode at LHC
We discuss the search for the heavy charged Higgs bosons H, implicitly of the Minimal Supersymmetric Standard Model, in the τν decay mode at the LHC. Compared to the dominant decay mode H → bt, the channel suffers from suppression due to the branching ratio and the lack of direct mass reconstruction, but the reduced Qcd background makes it a feasible channel especially in the large tan β region...
متن کاملPair production of charged Higgs bosons in the Left-Right Twin Higgs model at the ILC and LHC
Left-Right twin Higgs(LRTH) model predicts the existence of a pair of charged Higgs φ. In this paper, we study the production of the charged Higgs bosons pair φ at the International Linear Collider(ILC) and the CERN Large Hadron Collider(LHC). The numerical results show that the production rates are at the level of several tens fb at the ILC, the process e+e− → φ+φ− can produce the adequate dis...
