Violation in the B Meson System
نویسنده
چکیده
CP violation in B decays is reviewed in the Standard Model (SM) and beyond the SM. The present explanation of CP violation in terms of a phase in the Cabibbo-KobayashiMaskawa (CKM) matrix can be tested through a variety of CP asymmetries in neutral and charged B decays. Usually, new mechanisms of CP nonconservation enter via B−B mixing and violate SM constraints on the CKM parameters in a few characteristic ways. Different models can be partially distinguished by penguin-dominated B decay rate measurements. In radiative decays, large mixing-induced asymmetries may occur due to new contributions to the decay amplitude. Invited talk given at FCNC97, Santa Monica, CA, Feb. 19−21, 1997

Meson B fragmentation function with consideration of mass corrections
Study of B meson (meson with the bottom quark flavor) in Large Hadron Collider (LHC) is of special importance so that the detector LHCb is devoted to investigate these types of mesons. For this reason, in this paper we will study the production process of this meson in a phenomenological approach using the experimental data from electron-positron annihilation. In this regards, we shall calculat...
متن کاملTheoretical Overview of CP Violation in B-Meson Decay
After a brief look at CP violation in kaon decays, a short overview of CP violation in the B-meson system and of strategies to determine the angles of the unitarity triangles of the CKM matrix is given. Both general aspects and some recent developments are discussed, including B c → D ± s D and B → πK decays, as well as the Bd → π +π−, Bs → K +K− system. Invited plenary talk given at the 6th In...
متن کاملThe discovery of CP violation in B-meson decays
We present the KEK B-factory project, which discovered CP violation in B-meson decays and proved that the Kobayashi-Maskawa theory correctly explains CP violation in meson decays.

We present a measurement of the Standard Model CP violation parameter sin 2φ1 based on a 29.1 fb −1 data sample collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. One neutral B meson is fully reconstructed as a J/ψKS , ψ(2S)KS , χc1KS , ηcKS , J/ψKL or J/ψK ∗0 decay and the flavor of the accompanying B meson is identified from its decay product...
متن کاملExperimental Tests of Discrete Symmetries with Kaons and B-mesons
During the last decades, experiments using K mesons have provided precise measurements of CP violation parameters which are important inputs for the understanding of flavour physics. They include the measurements of Re(ε’/ε) by NA48 and KTeV experiments using KL and KS, the search for CP violation in K → 3π decays and rare decay processes allowing to search for new physics and to test chiral pe...
متن کاملTheoretical Review of CP Violation
The focus of our considerations is the B-meson system, which will provide stringent tests of the Kobayashi– Maskawa mechanism of CP violation in this decade. After a classification of the main possible strategies to achieve this goal, we discuss the status of the B-factory benchmark modes in view of the current experimental data. We shall then turn to the “El Dorado” for B-decay studies at hadr...
