Branching fractions and direct CP asymmetries of charmless decay modes at the Tevatron

We present new CDF results on the branching fractions and time-integrated direct CP asymmetries for $B^{0}$ and $B^{0}_{s}$ decay modes into pairs of charmless charged hadrons (pion or kaon). The data set for this update amounts to 1 fb$^{-1}$ of $\bar{p}p$ collisions at $\sqrt{s}=1.96 \rm{TeV}$. We report the first observation of the $B^{0}_{s} \to K^{-}\pi^{+}$ mode and a measurement of its branching fraction and direct CP asymmetry. We also observe for the first time two charmless decays of $b$-baryon: $\Lambda^{0}_{b} \to p\pi^{-}$ and $\Lambda^{0}_{b} \to pK^{-}$.Comment: Proceedings for Beauty 2006, Sept. 25-29 at Oxford University, to be published in Nucl.

Updated measurements of hadronic B decays at CDF

The CDF experiment at the Tevatron $p\bar{p}$ 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 provides 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 $B^- \to D(\to K^+\pi^-)\pi^-$.Comment: 5 pages,2 figures, proceedings for EPS-HEP 2011.

B Physics at the TeVatron

The CDF and D\O\ experiments at the Tevatron $p\bar{p}$ 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 provides a rich, and highly rewarding program that is currently reaching full maturity. I report a few recent world-leading results on rare decays, CP-violation in $B^0_s$ mixing, $b\to s$ penguin decays, and charm physics.Comment: 5 pages, 1 figure, proceedings for IFAE2011.

B Physics at the Tevatron

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)

CP and charge asymmetries at CDF

We present CDF results on the branching fractions and time-integrated direct CP asymmetries for B0 and B0s decay modes into pairs of charmless charged hadrons (pions or kaons). We report also the first observation of B0s->DsK mode and the measurement of its branching fraction.Comment: Proceedings of The 2007 Europhysics Conference on High Energy Physics Manchester, England 19-25 July 2007.

Measurement of CP Violation in D0/Dˉ0D^0/\bar{D}^0

Charm physics has played all along a central role in particle physics, however the level of attention on it has tremendously increased in the last years because of the observation of "fast" $D^0-\bar{D}^0$ flavour oscillations and because of very recent observed hints of CP violation. While in the past these would have been unambiguously interpreted as signs of New Physics, the revisitation of theoretical expectations, prompted by the latest experimental measurements, makes the picture not clear. This brief review covers the current status of CP-violating measurements in the $D^0-\bar{D}^0$ system, both on the experimental and theoretical side.Comment: 17 pages, 6 figures, 3 tables.
