Pages : 12
Book Description
The Fermilab Tevatron, operating at {radical}s = 1.96 TeV, provides a rich environment for the study of the bottom and charmed hadrons and for searches of other bound states. Presented here are recent measurements of the masses of the following states using fully reconstructed events: B{sup +}, B{sup 0}, B{sub s}, {Lambda}{sub b}, and the neutral B**. Lifetimes from both CDF and D0 in exclusive decays for all of these modes are also presented (sans the B**). A search was conducted at CDF for the {Xi}{sup 2} and {Xi}{sup 0} pentaquark states in the decay {Xi}(1860) {yields} {Xi}{sup -} {pi}{sup {+-}} setting a limit on their production in p-{bar p} collisions relative to the number of {Xi}(1530) baryons seen.

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. The CDF and D0 collaborations have more than 5 fb−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−1 of data.

Book Description
A measurement of b-hadron lifetimes in the fully reconstructed decay modes B 2!J/[psi]K+, B° 2!J/[psi]K*°, B° 2!J/[psi]K{sub S}°, and [Lambda]{sub b}° 2!J/[psi] [Lambda]° is reported using data corresponding to an integrated luminosity of 4.3 fb−1, collected by the CDF II detector at the Fermilab Tevatron. The measured values are [tau](B+) = 1.639 ± 0.009(stat) ± 0.009(syst) ps, [tau](B°) = 1.507 ± 0.010(stat) ± 0.008(syst) ps and [tau]([Lambda]{sub b}°) = 1.537 ± 0.045(stat) ± 0.014(syst) ps. The lifetime ratios are [tau](B+)/[tau](B°) - 1.088 ± 0.009(stat) ± 0.004(syst) and [tau]([Lambda]{sub b}°)/[tau](B°) = 1.020 ± 0.030(stat) ± 0.008(syst). These are the most precise measurements of these quantities from a single experiment. Observation is also reported for a structure near the J/[psi][phi] threshold, in B+ to J/[psi][phi]K+ decays with an integrated luminosity of 6.0 fb−1 and a statistical significance of 5 standard deviations. There are 19 ± 6 events observed for this structure at a mass of 4143.4{sub -3.0}{sup +2.9} ± 0.6 MeV/c2 and a width of 15.3{sub -6.1}{sup +10.4} ± 2.5 MeV/c2.

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
Lifetimes and masses of B mesons have been measured in exclusively reconstructed decays including J/[psi] [yields] [mu][sup +] decays. In 19.3 pb[sup [minus]1] of [bar p]p collisions at [radical]s = 1.8 TeV taken in 19920--93 at the Fermilab Tevatron collider, approximately 300 B mesons have been fully reconstructed. The measurements require precise determination of the helical track parameters of charged particle tracks. We find M(B[sub S][sup O]) = 5367.7 [plus-minus] 2.4 [plus-minus] 4.8 MeV/c[sup 2], [tau](B[sup +]) = 1.61 [plus-minus] 0.16 [plus-minus] 0.05 ps, and [tau](B[sup O]) = 1.57 [plus-minus] 0.18 [plus-minus] 0.08 ps.
