Implications of Non-Standard CP Violation in Hadronic B-Decays

چکیده
We investigate a class of models for new physics which could produce a large difference in sin 2β between B0 → J/ψKS and the “pure penguin” mode B0 → φKS . In such models, the dominant effect is through a Z-penguin and therefore a pattern of deviation in sin 2β as measured in B0 → χ1KS ; ηcKS ; J/ψKS and ψKS is predicted. If the preliminary data concerning the discrepancy between J/ψKS and φKS proves correct in magnitude, discrepancies in these other modes would likely be observable. We also consider the effects such new physics could have on the Bs system and the isospin analysis of B → Kπ. We compare this scenario with a scenario where contributions to sin 2β in various modes is produced by gluino loops and down squark mixing. * Work supported by DOE contract DE-FG02-94ER40817. email: [email protected] email: [email protected]

K(k)x: Decay Distributions, Branching Ratios and Cp Asymmetries
The semi-inclusive charmless hadronic decays B → K(K)X , where X is a hadronic recoil system containing no charmed and strange particles, are useful for studying direct CP violation and determining the weak phase γ . Direct CP violation can also be studied with exclusive or inclusive charmless hadronic B decays. Although theoretical uncertainties in inclusive decays may be small, it is experime...
متن کاملCP violation in B decays and supersymmetry
CP violation in hadronic B-decays is studied in a definite and well motivated framework for flavour physics and supersymmetry. Possible deviations from the standard model both in mixing and in decay amplitudes are discussed. An attempt is made to describe an experimental strategy for looking at these deviations and for measuring the relevant parameters.
متن کاملExploring CP Violation through B Decays
The B-meson system provides many strategies to perform stringent tests of the StandardModel description of CP violation. In this brief review, we discuss implications of the currently available B-factory data on the angles α, β and γ of the unitarity triangle, emphasize the importance of Bs studies at hadronic B experiments, and discuss new, theoretically clean strategies to determine γ. Invite...
متن کاملSLAC-PUB-11888 Rare hadronic B decays.
The study of rare hadronic B-meson decays with branching fractions O(10) enable us to probe a wide range of phenomena. Such decays can be used to probe our understanding of the CKM [1] description of quark mixing and CP violation (CPV ) in the Standard Model of Particle Physics (SM) by measuring all three of the Unitarity Triangle angles α, β and γ, as well as charge asymmetries in direct CPV ∆...
متن کاملTheory of hadronic B decays
The hadronic decays of B mesons provide a unique source of information about the flavor structure of the Standard Model. Due to the peculiar hierarchy structure of the CKM matrix, CP violation is an order unity effect in B decays. After several years of data taking from the B factories BABAR and BELLE, we are now in a position to perform precision tests of the CKM mechanism for CP violation. It...
متن کاملMeasurement of matter–antimatter di erences in beauty baryon decays
Di erences in the behaviour of matter and antimatter have been observed in K and B meson decays, but not yet in any baryon decay. Such di erences are associatedwith the non-invariance of fundamental interactions under the combined chargeconjugation and parity transformations, known as CP violation. Here, using data from the LHCb experiment at the LargeHadron Collider, we search for CP-violating...
