Book Description
The authors review recent results on heavy quark physics focusing on Run II measurements of B hadron spectroscopy and decay at the Tevatron. A wealth of new B physics measurements from CDF and D0 has been available. These include the spectroscopy of excited B states (B**, B**{sub s}) and the observation of the [Sigma]{sub b} baryon. The discussion of the decays of B hadrons and measurements of branching fractions focuses on charmless two-body decays of B 2!hh−. They report several new B{sub s}° and [Lambda]{sub b}° decay channels.

Book Description
Recent results on heavy flavor spectroscopy from the CDF and D0 experiments are reported in this contribution. Using up to 1 fb{sup -1} of accumulated luminosity per experiment, properties of X(3872), excited B** states, and the B{sub c} meson are measured. Also included are measurements of production rates for ground state b hadrons in p{bar p} collisions.

Book Description
After a five year upgrade period, the Fermilab experiments CDF and D0 are taking high quality data in Run II of the Tevatron Collider. We report on the start-up of both detectors and present a selection of first B physics results from the Tevatron. We also compare different B hadron producers such as the [Upsilon](4S) with the hadron collider environment and discuss general features of B physics at a hadron collider.

Book Description
The authors present a study of rates and kinematical properties of lepton pairs contained in central jets with transverse energy E{sub T} ≥ 15 GeV that re produced at the Fermilab Tevatron collider. They compare the data to a QCD prediction based on the HERWIG and QQ Monte Carlo generator programs. They find that the data are poorly described by the simulation, in which sequential semileptonic decays of single b quarks (b → l c X with c → l s X) are the major source of such lepton pairs.

Book Description
We present experimental results on b-hadron mass measurements and b-meson oscillations based on integrated luminosity of 250 to 450 pb{sup -1} of p{bar p} collisions at {radical}s = 1.98 TeV by the CDF and D0 collaborations at the TeVatron. The masses of b-hadrons have been measured precisely by the CDF collaboration in decays containing a J/{psi}. A blind search of the decay mode B{sub c} {yields} J/{psi}{pi}{sup +} resulted in a peak of 18.9 {+-} 5.4 candidates at a mass value of 6287.0 {+-} 4.5 {+-} 1.1 MeV/c{sup 2}. A new limit has been set to the decay B{sub d, s} {yields} {mu}{sup +}{mu}{sup -}. Both the CDF and D0 collaborations are in the position to put a limit on the frequency of the B{sub s} oscillations. D0 reports {Delta}m{sub s}> 5.0 ps{sup -1}.

Book Description
The Tevatron provides 1.96 TeV p{bar p} collisions and allows for collection of rich b-hadron samples to the two experiments CDF and D0. The study of heavy flavor properties represents a fruitful opportunity to investigate the flavor sector of the Standard Model (SM) and to look for hints of New Physics (NP). Here we report the first measurement of polarization amplitudes in B{sub s}° charmless decays, world leading results on b-hadron lifetimes, and measurements of several other properties of b-hadrons.

Book Description
The lectures collected in this book present a comprehensive review of the current knowledge of heavy-quark physics, from the points of view of both theory and experiment. Heavy Flavour Physics has accomplished enormous progress during the last few years: the last heavy quark has been discovered and the quality of the collected data on the other relatively lighter quarks has dramatically improved. On the theory side, noticeable progress has been reported on new calculations of decay rates based on various techniques, such as QCD sum rules, heavy-quark mass expansion and lattice QCD. The theory of heavy quark production is constantly improving and awaiting new results. Nevertheless there are strong reasons to believe that the Standard Model of High Energy Physics is incomplete. It exhibits very peculiar patterns for which it offers no explanation. The basic constituents of matter are arranged into three seemingly identical generations or families of quarks and leptons, differing merely in their masses. The pattern in the fermion masses, why they are families and why there are three of them is not yet understood. Furthermore it is known that at least within the standard model there is an intimate connection between the replication of families and the gateway of CP violation, in addition, the latter phenomenon is a crucial ingredient in explaining why our universe is made up almost exclusively of matter rather than being more or less matter-antimatter symmetric. How and to what extent can Heavy Flavour Physics impact on these questions? Does it offer novel windows onto New Physics beyond the Standard Model in general and onto new symmetries, such as Supersymmetry in particular? These questions constitute the central theme of this book. The material treated in this publication may serve as reference for the segment of the high-energy community actively engaged in heavy-quark physics.
