CP-odd invariants in models with several Higgs doublets
نویسنده
چکیده
We present CP-odd Higgs-basis invariants, which can be used to signal CP violation in a multi-Higgs system, written in an arbitrary Higgs basis. It is shown through specific examples how these CPodd invariants can also be useful to determine the character of CP breaking (i.e. whether it is hard or soft CP breaking) in a given Higgs Lagrangian. We analyse in detail the cases of two and three Higgs doublets.

متن کاملTWO HIGGS DOUBLETS MODELS AND CP VIOLATING HIGGS EXCHANGE IN e + e − → t¯tZ
Appreciable CP Asymmetries (∼ 10%) can arise in the reaction e + e − → t ¯ tZ already at tree-level in models with two Higgs doublets. For a neutral Higgs particle, h, with a mass in the range 50 GeV ∼ < m h ∼ < 400 GeV, it may be possible to detect a 2–3 sigma CP-odd effect in e + e − → t ¯ tZ in ∼ 1 − 2 years of running of a future high energy e + e − collider with c.m. energies of ∼ 1 − 2 Te...
متن کاملCP-Violation with Bosons
We formulate the conditions under which a purely bosonic theory (without fermions) containing neutral spin-0 particles and vector (gauge) bosons violates the CP-symmetry through the presence of CP-even and CP-odd operators in the Lagrangian. This is done without reference to explicitly CP-violating scalar sector of extended standard models (SM) with two or more Higgs doublets. The Lagrangian ex...
متن کاملZu–th 5/98 Pm–98/1 Lower Bounds on Charged Higgs Bosons from Lep and Tevatron
We point out that charged Higgs bosons can decay into final states different than τντ and cs̄, even when they are light enough to be produced at LEP or at the Tevatron, through a t–quark decay. These additional decay modes are overlooked in ongoing searches and alter existing lower bounds on the mass of charged Higgs bosons present in supersymmetric and two Higgs doublets models. The discovery o...

We point out that charged Higgs bosons can decay into final states different from τντ and cs̄, even when they are light enough to be produced at LEP II or at the Tevatron through top quark decays. These additional decay modes are overlooked in ongoing searches even though they alter the existing lower bounds on the mass of the charged Higgs bosons that are present in supersymmetric and two Higgs...
