How to extract CP-violating asymmetries from angular correlations.

چکیده
Large CP-violation effects can occur for time-evolved B decays into definite CP eigenstates. The rates into these unique CP eigenmodes are tiny. This article advocates the use of many additional modes that are not CP eigenstates because of mixtures of angular momenta. Naively, for those modes a partial and sometimes large cancellation of the CP asymmetry occurs. However, a detailed study of their angular correlations enables the projection onto definite CP eigenstates, and thus recovers the full CP asymmetry.

متن کاملP and T Odd Asymmetries in Lepton Flavor Violating τ Decays
We calculated the differential cross sections of the processes in which one of the pair created τ particles at an e+e− collider decays into lepton flavor violating final states e.g. τ → μγ, τ → 3μ, τ → μee. Using the correlations between angular distributions of both sides of τ decays, we can obtain information on parity and CP violations of lepton flavor non-conserving interactions. The formul...
متن کاملSymmetry Tests in Polarized Z 0 Decays to B Bg the Sld Collaboration
Angular asymmetries have been measured in polarized Z 0 decays to b bg collected by the SLD experiment at the SLC. A high purity b bg event sample is selected utilizing lifetime information given by the SLD CCD pixel vertex detector and the stable micron-size SLC beams, and the band b-jets are identiied using lifetime information and momentum-weighted track charge. Parity violating asymmetries ...
متن کاملCP property of the Higgs at the γγ colliders using tt̄ production
CP property of the Higgs at the γγ colliders using t ¯ t production. ABSTRACT We present results of an investigation to study CP violation in the Higgs sector in t ¯ t production at a γγ-collider, via the process γγ → φ → t ¯ t where the φ is a scalar with indeterminate CP parity. The study is performed in a model independent way parametrising the CP violating couplings in terms of six form fac...
متن کاملParticle-width effect on CP-violating asymmetries.
CP -violating asymmetries calculated from the Breit-Wigner approximation for unstable particle propagators violate CPT . A formalism satisfying CPT invariance and unitarity is presented. Applications are given to t decays. For the decay t → bντ τ̄ in a class of CP -violating Higgs models the CP -violating asymmetry turns out to be 10−4 times smaller than the previously reported results. PACS#: 1...
