Probing Mssm Higgs Sector Cp Violation at a Photon Collider *
We study the phenomenological implications of the Higgs sector CP violation at a photon collider. In our model, the CP violation is radiatively induced by the non–trivial CP phases of the third–generation scalar–quark sector in the MSSM. We re–evaluate the s–channel resonance production cross sections and the polarization asymmetries of the neutral Higgs bosons based on the calculation of the m...
متن کاملProbing Higgs-sector Cp Violation at a Photon Collider
The two-photon collision option of the International Linear ee Collider (ILC), a photon linear collider (PLC), is using back-scattered laser photons off the incident electrons and/or positrons. 1,2 A photon collider provides unique capabilities for probing new physics appearing in neutral spin-zero particles such as neutral Higgs bosons in the Standard Model (SM) and its Minimal Supersymmetric ...
متن کاملErratum: Probing Higgs sector CP violation with top quarks at a photon linear collider
We investigate for two-Higgs doublet models with intrinsic CP violation in the scalar potential CP-nonconserving eeects in unpolarized ! t t for a range of neutral Higgs boson masses which includes resonant ' production and the subsequent decay of ' ! t t. The importance of taking into account, even in the resonant case, the interference with the nonresonant background is shown. Further, we pro...
متن کاملProbing MSSM Higgs Sector with Explicit CP Violation at a Photon Linear Collider
The CP properties of Higgs bosons can be probed through their s–channel resonance productions via photon–photon collisions by use of circularly and/or linearly polarized backscattered laser photons at a TeV–scale linear e+e− collider. Exploiting this powerful tool, we investigate in detail the Higgs sector of the minimal supersymmetric Standard Model with explicit CP violation. PACS number(s): ...
متن کاملHiggs Sector in Extensions of the Minimal Supersymmetric Standard Model
Extensions of the minimal supersymmetric standard model (MSSM) with additional singlet scalar fields solve the important μ-parameter fine-tuning problem of the MSSM.We compute and compare the neutral Higgs boson mass spectra, including one-loop corrections, of the following MSSM extensions: next-tominimal supersymmetric standard model (NMSSM), the nearly-minimal supersymmetric standard model (n...
