We present the latest B physics results from the CDF experiment at the Fermilab Tevatron collider. We focus on a number of analyses, including a measurement of the forward-backward asymmetry of B -> K^(*) mu mu decays, determination of the CP violating phase sin2beta_s in B^0_s-> J/psi phi decays, B -> J/psi X lifetime measurements, observation of resonance structure in Lambda_b -> Lambda_c 3pi, and Upsilon(1S) polarization.

I report recent measurements in b-hadron decays reconstructed in the full data set of sqrt{s} = 1.96 TeV proton-antiproton collisions collected by the CDF experiment at the Tevatron. These include the final CDF results on: measurements of CP asymmetr
ies in two-body charmless decays of the Bd, Bs, and Lambda^0_b hadrons; bounds on the Bs mixing phase and on the decay width difference of Bs mass eigenstates; and updated measurements of branching ratios of Bs->Jpsi Phi and Bs->Ds(*)Ds(*) decays. All measurements are among the most precise from a single experiment and in agreement with the standard model predictions.
The CDF experiment at the Tevatron $pbar{p}$ collider established that extensive and detailed exploration of the $b$--quark dynamics is possible in hadron collisions, with results competitive and supplementary to those from $e^+e^-$ colliders. This p
rovides a rich, and highly rewarding program that has currently reached full maturity. In the following I report some recent results on hadronic decays: the evidence for the charmless annihilation decay mode $B^0_s to pi^+pi^-$, and the first reconstruction in hadron collisions of the suppressed decays $B^- to D(to K^+pi^-)K^-$ and $B^- to D(to K^+pi^-)pi^-$.
This report presents the results of studies that investigate the physics reach at a Super $B$ factory, an asymmetric-energy $e^+e^-$ collider with a design luminosity of $8 times 10^{35}$ cm$^{-2}$s$^{-1}$, which is around 50 times as large as the pe
ak luminosity achieved by the KEKB collider. The studies focus on flavor physics and CP violation measurements that could be carried out in the LHC era. The physics motivation, key observables, measurement methods and expected precisions are presented.
The B-physics program at the ATLAS experiment, which covers the mid-rapidity region, complements that at the dedicated LHCb experiment, which covers the forward rapidity region. At the early stage of the LHC operation, the program concentrated on und
erstanding of detector performance and measurements of quarkonia and D mesons. This article presents recent results of the B-physics program at ATLAS.
The Fermilab Tevatron offers unique opportunities to perform measurements of the heavier b-hadrons that are not accessible at the Y(4S) resonance. In this summary, we describe most important heavy flavor results from DO and CDF collaborations and we
discuss prospects for future measurements, that could reveal New Physics before the start-up of the Large Hadron Collider (LHC).
