CP-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 کاملBosons with Explicit CP Violation
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 effects 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 modifies the...
متن کاملNeutral Higgs bosons in the MNMSSM with explicit CP violation
Within the framework of the minimal non-minimal supersymmetric standard model (MNMSSM) with tadpole terms, CP violation effects in the Higgs sector are investigated at the one-loop level, where the radiative corrections from the loops of the quark and squarks of the third generation are taken into account. Assuming that the squark masses are not degenerate, the radiative corrections due to the ...

متن کاملCP violation in the cubic coupling of neutral gauge bosons.
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.
