Available in PDF, EPUB and Kindle. Book excerpt: 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.

Likewise the measurement of the B{sub d} oscillation frequency has been updated. New limits on the B{sub s} oscillation frequency have been determined using for the first time Run II data.

Book excerpt: During the run period from May 1992 to begin of June 1993 the Collider Detector at Fermilab (CDF) has recorded ≈ 21.4 pb−1 of p{anti p} collider data at √s = 1.8 TeV. For this run the detector had been upgraded which significantly enhanced its b-physics capabilities. The upgrades include a high precision Silicon VerteX detector (SVX) which enables CDF to reconstruct the decay vertex and decay length of b-hadrons. In this article the author reports on several measurements of the lifetime of b-flavored hadrons. The determination of the average b-lifetime using inclusive J/??s, the measurement of the B{sup {+-}} and B° lifetimes by reconstructing exclusive final states including a J/? or?(2S) and a measurement of the B{sub s}° meson lifetime exploiting the decay: B{sub s} → l?D{sub s} → l???+ → l?K+K−?+.

Download or read book Flavor Physics at the Tevatron written by Thomas Kuhr and published by Springer. This book was released on 2012-09-30 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

Book excerpt: The Tevatron experiments, CDF and D0, have produced a wealth of new B-physics results since the start of Run II in 2001. We've observed new B-hadrons, seen new effects, and increased many-fold the precision with which we know the properties of b-quark systems. In these proceedings, we will discuss two of the most fruitful areas in the Tevatron B-physics program: lifetimes and mixing. We'll examine the experimental issues driving these analyses, present a summary of the latest results, and discuss prospects for the future.
