Title: Spectroscopy and Decay of $B$ Hadrons at the Tevatron

Abstract

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 {yields} h{sup +}h{sup -}. They report several new B{sub s}{sup 0} and {Lambda}{sub b}{sup 0} decay channels.

  • 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}{sup 0} charmless decays, world leading results on b-hadron lifetimes, and measurements of several other properties of b-hadrons.
  • The latest results in B physics from the CDF and D0 experiments at the Tevatron are presented, including inclusive b lifetime measurement, exclusive lifetime measurement of the B{sub s}. Promising samples collected by CDF with its Secondary Vertex Trigger are shown as well.
  • The latest results for the B Hadron sector at the Tevatron Collider are summarized. The properties of B hadrons can be precisely measured at the Tevatron. In particularly they will focus on the masses and lifetimes. The new Tevatron results for the CP violation in B Hadrons are also discussed.
  • The Tevatron, with p{bar p} collisions at {radical}s = 1.96 TeV, can produce all flavors of B hadrons and allows for unprecedented studies in the B physics sector. The CDF and D0 collaborations have more than 5 fb{sup -1} of data recorded. I present here a selection of recent results on the masses, lifetimes and mixings of B hadrons using between 1.0 and 2.8 fb{sup -1} of data.
  • 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.
