Book Description
The Tevatron experiments CDF and D0 have filled many empty spots in the spectrum of heavy baryons over the last few years. The most recent results are described in this article: The first direct observation of the?{sub b}°, improved measurements of?{sub b} properties, a new measurement of the?{sub b} → J/?? branching ratio, and a high-statistics study of charm baryons.

Book Description
Precision measurements of the masses and widths of the bottom baryon resonances [Sigma]{sub b} and [Sigma]*{sub b} and charm baryons [Lambda]{sub c}(2595), [Lambda]{sub c}(2625), [Sigma]{sub c}(2455), and [Sigma]{sub c}(2520) are reported. A new measurement of [Lambda]{sub b} production is described. The studies include the first measurement of the widths and isospin mass splittings of the members of the [Sigma]{sub b} family. The charm baryons are examined through their strong decays to the [Lambda]{sub c} ground state, and measurements of their mass differences relative to the ground state, and corresponding decay widths, are reported. The data were collected by the CDF and D0 detectors for 1.96 TeV proton-antiproton collisions during Run II at the Fermilab Tevatron.

Book Description
The CDF and D0 experiments have produced a wealth of heavy flavor physics results since the beginning of RunII of the Fermilab Tevatron. They review recent measurements of B hadron states including excited B states (B**, B{sub s}**) and the B{sub c} meson. They also summarize the discoveries of the [Sigma]{sub b} baryon states and the [Xi]{sub b}− baryon.

Book Description
The physics of heavy flavors is a very active area of research in experimental and theoretical high energy physics. A number of heavy flavor experiments at new or upgraded accelerators are just coming on line to address some of the most fundamental questions of particle physics, e.g. matter-anti-matter asymmetry (CP violation).The Seventh International Symposium on Heavy Flavor Physics focused primarily on the physics of bottom and charmed quarks, but there were also sessions on the top quark and the tau lepton. It presented a great opportunity to take stock of the field on the eve of the new era in heavy flavor physics which will be opened up by the next generation of experiments.

Book Description
The symposium focused on the following hot topics of particle physics, such as heavy flavor productions and decays; QCD corrections; EW symmetry breaking theories; precise tests of Standard Model and physics beyond Standard Model; CP violation and rare decays etc. There are 30 talks presented at the symposium by participants from all over the world, who are active in the forefront of the fields.

Book Description
The book reviews the latest experimental results of charm and bottom flavor physics at the Tevatron proton-antiproton collider. The measurements of lifetimes, branching ratios and mixing properties of heavy flavored hadrons provide important constraints on fundamental parameters of the standard model – the elements of the CKM matrix. Comparisons of experimental results with theoretical predictions allow to search for physics beyond the standard model or to set bounds on parameters of new physics models. The experimental techniques developed at the Tevatron are highly relevant for the next generation flavor physics experiments at the LHC. This book provides the reader a detailed summary of the status of heavy flavor physics at the end of the Tevatron data taking period and the start of the LHC program.

Book Description
The Tevatron at Fermilab continues to collect data at high luminosity resulting in datasets in excess of 6 fb−1 of integrated luminosity. The high collision energies allow for the observation of new heavy quark baryon states not currently accessible at any other facility. In addition to the ground state [Lambda]{sub b}, the spectroscopy and properties of the new heavy baryon states [Omega]{sub b}, [Xi]{sub b}, and [Sigma]{sub b}{sup (*)} as measured by the CDF and D0 Collaborations are presented.

Book Description
The Tevatron, with p{bar p} collisions at (square root)s = 1.96 TeV, can produce all flavors of B hadrons and allows for unprecedented studies in the B physics sector. These range from measurements of B hadron properties to searches of new physics signatures. The CDF1 and D02 detectors currently have more than 7 fb−1 of data recorded. This paper presents a selection of recent results on lifetimes and flavor changing neutral currents using between 4.3-5.0 fb−1 of data.
