Book Description

The Tevatron collider at Fermilab provides a rich environment for B spectroscopy. Recently the first direct observation of the B{sub c} meson has reduced its mass uncertainty by two orders of magnitude. A search for [eta]{sub b} mesons provides the best limit on its production in p{bar p} colliders. In studies on orbitally excited B{sub d} mesons for the first time the narrow states could be separated from each other. The orbitally excited B{sub s} mesons have been observed for the first time. With the charged [Sigma]{sub b}{sup (*)} a second B baryon could be established beside the [Lambda]{sub b}.

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

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 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

We review recent results in heavy quark hadron spectroscopy at the Tevatron. With increasing data samples, the Tevatron experiments start to uncover information on the spectroscopy of b-hadrons. Most important are the first observations of the narrow B**{sub s}° as well as [Sigma]{sub b}{sup {+-}}, [Sigma]*{sub b}{sup {+-}} and [Xi]{sub b}− baryons. In addition we present updated results on the narrow B**° and B{sub c} mesons.

Book Description

In this paper recent results from the CDF and D0 experiments on heavy flavor spectroscopy are reported. Both experiments are using up to 1.1 fb{sup -1} of data delivered by the Tevatron proton-antiproton collider at the Fermi National Accelerator Laboratory, Batavia, IL, USA. The CDF and D0 detectors are described in references [1,2].

Book Description

Using data from p{bar p} collisions at √s = 1.96 TeV recorded by the CDFII and D0 detectors at the Fermilab Tevatron, we present recent results on charm and bottom hadrons. The most recent CDF results on properties of the four bottom baryon resonant states [Sigma]{sub b}{sup (*)-}, [Sigma]{sub b}{sup (*)+}. New results on exotic [Upsilon](4140) state observed by CDF are also reported. A precise measurement of production rates of the lowest lying bottom baryon, [Lambda]{sub b}°, produced in the D0 detector is presented.

Book Description

This proceedings volume is devoted to a wide variety of items, both in theory and experiment, of particle physics such as tests of the Standard Model and beyond, physics at the future accelerators, neutrino and astroparticle physics, heavy quark physics, non-perturbative QCD, quantum gravity effects and cosmology. It is important that the papers in this volume reveal the present status and new developments in the above-mentioned items on the eve of a new era that starts with the Large Hadron Collider (LHC).

Book Description

Between 1992 and 1996, the CDF and D0 experiments have collected data samples of 110 pb−1 each of p{bar p} collisions at (square root)s = 1.8 TeV at the Fermilab Tevatron. In the year 2001 the Tevatron commenced p{bar p} collisions again at (square root)s = 1.96 TeV with the goal of delivering an integrated luminosity of 1 fb−1 per year. In the mean time the CDF and D0 detectors have undergone substantial upgrades which allow for a rich B physics program with unique capabilities. In this paper we discuss recent results and the B Physics prospects at the Tevatron with 2 fb−1 of data (Run IIa) or 15 fb−1 of data (Run IIa+Run IIb).
