چکیده

We present measurements of branching fractions and charge asymmetries for charmless B-meson decays to three-body final states of charged pions and kaons. The analysis uses 81.8 fb(-1) of data collected at the Upsilon(4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. We measure the branching fractions B(B+-->pi(+)pi(-)pi(+))=(10.9+/-3.3+/-1.6)x10(-6), B(B+-->K+pi(-)pi(+))=(59.1+/-3.8+/-3.2)x10(-6), and B(B+-->K+K-K+)=(29.6+/-2.1+/-1.6)x10(-6) and provide 90% C.L. upper limits for other decays. We observe no charge asymmetries for these modes.

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 and B s decay modes into pairs of charmless charged hadrons (pion or kaon). The data set for this update amounts to 1 fb of p̄p collisions at √ s = 1.96 TeV. We report the first observation of the B s → K π mode and a measurement of its branching fraction and direct CP asymmetry. We also observe...

Measurements of branching fractions and CP - violating asymmetries in B 0 → π + π − , K + π − , K + K − decays

Recent measurements of the CP -violating asymmetry parameter sin2β by the BABAR [1] and BELLE [2] collaborations established CP violation in the B system. These measurements, as well as updated preliminary results [3, 4], are consistent with the Standard Model expectation based on measurements and theoretical estimates of the elements of the Cabibbo-Kobayashi-Maskawa [5] (CKM) quark-mixing matr...

Measurements of CP violation in the three-body phase space of charmless B decays

The violation of CP symmetry is well established experimentally in the quark sector and, in the Standard Model (SM), is explained by the Cabibbo-KobayashiMaskawa [1] matrix through the presence of a single irreducible complex phase. Although the SM is able to describe all CP asymmetries observed experimentally in particle decays, the amount of CP violation within the SM is insufficient to expla...

Hadronic Bu and Bd decays

The PEP-II and KEKB B factories have very recently produced a number of new measurements or limits for B decay modes to hadronic final states. These include some b → c modes bearing on the interpretation of experiments aiming to measure the CKM angle γ (φ3), charmless baryonic three-body final states with their two-body substructure, and a number of charmless mesonic branching fractions and cha...

Charmless non - leptonic B s decays to PP , PV and V V final states in the pQCD approach

Abstract We calculate the CP-averaged branching ratios and CP-violating asymmetries of a number of two-body charmless hadronic decays B0 s → PP,PV, V V in the perturbative QCD (pQCD) approach to leading order in αs (here P and V denote light pseudoscalar and vector mesons, respectively). The mixinginduced CP violation parameters are also calculated for these decays. We also predict the polariza...
