Measurement of Angular Asymmetries in the Decays B →

Penguin trapping with isospin analysis and CP asymmetries in B decays.

Isospin relations are used to eliminate hadronic uncertainties in various CP asymmetries in 8 decays. In addition to the simple triangle relations for the m.m mode, we study quadrilateral relations for Km and pentagon relations for pm. A combined angular and isospin analysis is required for pp. These methods are useful also for three-body decays such as Kmm. . The magnitude of the penguin ampli...

Lepton angular asymmetries in semileptonic charmful B decays

CP Asymmetries in Higgs decays to ZZ at the LHC

We examine the effect of a general HZZ coupling through a study of the Higgs decay to leptons via Z bosons at the LHC. We discuss various methods for placing limits on additional couplings, including measurement of the partial width, threshold scans, and asymmetries constructed from angular observables. We find that only the asymmetries provide a definitive test of additional couplings. We furt...

B Hadronic Asymmetries and Spin Correlations

Asymmetries in neutral B decays to CP eigenstates offer the possibility of providing particularly clean CP violation tests. We point out that, in certain circumstances, this is also possible even when the final state is not a CP eigenstate. For these purposes, one needs to use final state angular distribution intbrmation to kinematically disentangle pure CP combinations. Various illustrative ex...

Symmetry 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 ...
