B-physics results from the CDF Collaboration based on data collected during the Tevatron run 1A and 1B are presented. In particular we discuss the measurements of B meson masses and lifetimes, the limits set on rare B decay branching ratios and B{sub o}{bar B}{sub o} mixing results obtained with both time-integrated and time-evolution analysis. We use the current results to extrapolate CDF B-physics prospects to the end of run 1 and to the future high luminosity run II.
This volume reviews the recent progress of B physics, and discusses theoretical and experimental aspects of the physics which will be explored at the B factory. CP violation and new physics beyond the Standard Model are the main issues of the discussion.
Current CDF b-physics results are presented. The analysis is based on data corresponding to an integrated luminosity of 4.4 pb−1 recorded with the CDF detector in 88--89 at the Fermilab Tevatron p{bar p} collider (√{bar s} = 1.8 TeV). Preliminary results include the differential cross section {sub dPt}/{sup d{sigma}(b)}, some reconstructed exclusive B-decays, a limit for the rare decay B° →??− and a measurement of B{bar B}-mixing parameters. Finally we will discuss the prospects concerning b-physics for the next data run which will start in February 1992. 12 refs., 8 figs.
This book provides a thorough introduction to the phenomenology of heavy flavour physics, those working on the B-factories, LHCb, BTeV, HERA and the Tevatron. It explains how heavy quark theory could be implemented on the lattice, and discusses the status of CP-violation in the neutral kaon system.
Preliminary results from two recent CDF b physics analyses are presented. The first obtains sin(2[beta])=0.79+0.41-0.44 from a measurement of the asymmetry in B0, [anti B0] [yields] J/[psi]K0s decays, providing the best direct indication so far that CP invariance is violated in the b sector. The second obtains new results on the parity even (A0 and A[parallel]) and odd (A[perpendicular]) polarization amplitudes from full angular analyses of B0 [yields] J/[psi]K*0 and B0s [yields] J/[psi][phi] decays: B0: [A0 = 0.770 " 0.039 " 0.012; A[parallel] = (0.530 " 0.106 " 0.034)e(2.16 " 0.46 " 0.10)i; A[perpendicular] = (0.355 " 0.156 " 0.039)e( -0.56 " 0.53 " 0.12)i], B0s: [A0 = 0.778 " 0.090 " 0.012; A[parallel] = (0.407 " 0.232 " 0.034)e(1.12 " 1.29 " 0.11)i; [vert-bar]A[perpendicular] = 0.478 " 0.202 " 0.040.
CP violation was first observed in 1964, but only in 1999 did we gain much greater experimental insight. Direct CP violation finally appeared in the form of ε′/ε in the K system. Indirect CP violation in B → J/Ψ Ks decay, the raison d'être for construction of e+e- B factories, was first sniffed out at the proton-antiproton collider. The asymmetric B factories — BABAR at SLAC and BELLE at KEK — were completed, while the symmetric B factory at Cornell was upgraded to CLEO-III. It seems that everyone is positioning himself for the great competition on “B Physics and CP Violation”, racing to unravel the Kobayashi-Maskawa matrix, especially the size and origin of CP phases. The change of millennium provides a dramatic backdrop.To have intensive discussions at the technical level, to create broader interest in the subject, and to maximize interaction between experimenters and theorists, this book starts with the status of B factories: accelerator, detector and physics analysis. Following an overview of B physics and the CKM matrix, it delves into the details of lifetime, spectroscopy and decays, with even more specialized discussions on rare decays, direct and indirect CP violation, factorization and final state interactions, determination of unitarity phases, etc. Topics on ε′/ε, rare K decay, charm and hyperon systems, and various T, CP and CPT tests are also discussed at length. The book closes with the outlook for hadron machines and the prospects for new physics. A special feature is that there are two summary talks, one on experiment and the other on theory. The book is further augmented by two dozen excellent contributed talks.
This book discusses recent developments in both the theoretical and the experimental aspects of QCD. Its main goal is to establish precise predictions of the Standard Model in order to find clues to the discovery of New Physics.
During the Run 1 data taking period, from 1992 through 1995, CDF has acquired 110 pb−1 of p{anti p} collisions at a center of mass energy of 1,800 GeV. This data has provided many results on B physics, and provides a basis for extrapolating to Run 2, which is scheduled to start in 1999 after major upgrades to both the accelerator and detector. The authors present herein a summary of Run 1 results relevant to an analysis of the CP asymmetry in B → J/[psi]K{sub s}, the CDF upgrade plans for Run 2, and some of the main B physics goals related to the exploration of the origin of CP violation.
