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 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 ...
متن کاملSoft-gluon resummation for Higgs boson production at hadron colliders
We consider QCD corrections to Higgs boson production through gluon–gluon fusion in hadron collisions. We compute the cross section, performing the all-order resummation of multiple soft-gluon emission at next-to-next-to-leading logarithmic level. Known fixed-order results (up to next-to-next-to-leading order) are consistently included in our calculation. We give phenomenological predictions fo...
متن کاملHiggs Boson Production at Hadron Colliders: Signal and background Processes
We review the theoretical status of signal and background calculations for Higgs boson production at hadron colliders. Particular emphasis is given to missing NLO results, which will play a crucial role for the Tevatron and the LHC.
متن کاملNLO Electroweak Corrections to Higgs Boson Production at Hadron Colliders
We present the complete two-loop electroweak corrections to gg → H, the main partonic channel for the production of the Higgs boson at hadron colliders. The evaluation is based on a numerical approach and the result covers all kinematical regions, including WW and ZZ thresholds, by introducing complex masses for the W and the Z bosons. Furthermore the relation between physical observables measu...
