CP violation in the cubic coupling of neutral gauge bosons.

چکیده
We investigate the CP violating form factor of the ZZZ and ZZ vertices in the pair production of Z bosons. Useful observables in azimuthal distributions are constructed to probe CP nonconservation which may originate from these vertices. A simple Two Higgs Model of CP violation is used as an illustration.

Spontaneous CP violation in the supersymmetric Higgs sector.
Spontaneous CP–violation in the minimal supersymmetric standard model with a gauge singlet and a cubic superpotential is examined. Although the tree–level Higgs potential conserves CP, it is shown that with the inclusion of the one–loop top–quark radiative effects , CP may be broken spontaneously. The CP–violating minimum requires two neutral (h 1 , h 2) and one charged (H ±) Higgs–bosons to be...
متن کاملCollider Probes of the MSSM Higgs Sector with Explicit CP Violation
We investigate the hadron collider phenomenology of the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violation for Higgs bosons that can be observed in Standard Model search channels: W/ZHi(→ bb̄) at the Tevatron, and gg → Hi(→ γγ), tt̄Hi(→ bb̄) and WW → Hi(→ τ+τ−) at the LHC. Our numerical analysis is based on a benchmark scenario proposed earlier called CPX, which has been desig...
متن کاملCP Violation in Tau Slepton Pair Production at Muon Colliders
We discuss in detail signals for CP violation in the Higgs boson and tau–slepton sectors through the production processes μ+μ− → τ̃ i τ̃ j , where i, j = 1, 2 label the two τ slepton mass eigenstates in the minimal supersymmetric standard model. We assume that the soft breaking parameters of third generation sfermions contain CP violating phases, which induce CP violation in the Higgs sector thro...
متن کاملThe neutral Higgs boson masses of MSSM at one-loop level in explicit CP violation scenario
The neutral Higgs sector of the minimal supersymmetric standard model (MSSM) in explicit CP violation scenario is investigated at the one-loop level. Within the context of the effective potential formalism, the masses of the neutral Higgs bosons are calculated at the one-loop level by taking into account the contributions of the following loops of ordinary particles and superpartners: top quark...
متن کاملDecays of the MSSM Higgs Bosons with Explicit CP ViolationS
We study Higgs boson decays in the minimal supersymmetric standard model where the tree-level CP invariance of the Higgs potential is explicitly broken by loop eeects of soft CP-violating Yukawa interactions related to scalar quarks of the third generation. The scalar-pseudoscalar mixing among two neutral CP-even Higgs bosons and one CP-odd Higgs boson due to explicit CP violation modiies their...
