Neutral Higgs Cp Violation at + Colliders
CP violating asymmetries in both the production and the decays of s-channel neutral Higgs bosons at + colliders can be large. If the CP violation occurs in the muon-Higgs coupling, one observes a production asymmetry with transversely polarized + beams. Likewise if the CP violation occurs in the top-Higgs or -Higgs coupling, one observes an azimuthal decay asymmetry in + ! t t (or + ). CP studi...
متن کاملTesting Cp Violation in the Higgs Sector at Muon Colliders
We study the possibility of measuring the muon Yukawa couplings in s-channel Higgs boson production at a muon collider with transversely polarized beams. We investigate sensitivity to the relative size of the CP-odd and CP-even muon Yukawa couplings. Provided the event rate observed justifies the operation of the μμ Higgs boson factory, we find that 40% polarization for both beams is sufficient...
متن کاملHiggs – 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 کاملProspects for Measurements of Cp Violation at Hadron Colliders
In the Standard Model, CP violation (CPV) arises from the clash of the Yukawa couplings with the charged current interaction. When the Lagrangian is written in the physical (mass) basis, this shows up as an irremovable phase in the CKM 1 quark mixing matrix. The magnitudes of most CKM matrix elements are constrained experimentally , and exhibit an hierarchy, with the magnitudes getting smaller ...
متن کاملCP Violation in Top Quark Pair Production at Hadron Colliders
CP violating effects in top quark pair production at the future 2 TeV pp̄ Tevatron and 14 TeV pp LHC colliders are investigated. We study three kinds of CP violating sources: the supersymmetric CP-odd phase of the stop trilinear soft breaking term: arg(At), the CP-odd parameter in two-Higgs doublet extensions of the standard model(2HDM), and the model-independent top quark chromoelectric dipole ...
