Abstract

Results of recent searches for new physics in CP violation in charm decays from the BABAR experiment are presented. These results include a measurement of D⁰ - anti D⁰ mixing and searches for CP violation in two-body D⁰ decays, a search for CP violation in the charm decays D^± → K_S⁰K ^± and D_s^± → K_S⁰K^± , K_S⁰π^± , and a search for direct CP violation in the singly-Cabibbo suppressed D^± → K⁺K^-π^±decays. These studies are based on the final dataset collected by BABAR at the PEP-II B factory at SLAC in the period 1999-2008. No evidence of CP violation is found in these charm decays. The measured mixing parameter y_CP = [0.72 ± 0.18(stat) ± 0.12(syst)]% excludes the no-mixing null hypothesis with a significance of 3.3σ .

BaBar Explores CP Violation

Technical Report Karyotakis, Jean

The most recent results obtained by the BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC on CP-violating asymmetries and branching fractions for neutral and charged B decays are presented here. The analysis was performed on a data sample of {approx} 88 million {Upsilon}(4S) {yields} B{bar B} decays collected between 1999 and 2002. Using b {yields} c{bar c}s decays, we measure sin2{beta} = 0.741 {+-} 0.067(stat) {+-} 0.034(syst). We also present sin2{beta} measurements from, b {yields} s{bar s}s and b {yields} c{bar c}d processes. From neutral B meson decays to two-body final states of charged pions and kaons, wemore »« less

First observation of CP violation in B¯⁰ → D^(*)_CP h⁰ decays by a combined time-dependent analysis of BaBar And Belle Data

Journal Article Abdesselam, A. - Physical Review Letters

We report a measurement of the time-dependent CP asymmetry of B¯⁰ → D^(*)_CPh⁰ decays, where the light neutral hadron h⁰ is a π⁰, η, or ω meson, and the neutral D meson is reconstructed in the CP eigenstates K⁺K^–, K⁰_Sπ⁰, or K⁰_Sω. The measurement is performed combining the final data samples collected at the Υ(4S) resonance by the BABAR and Belle experiments at the asymmetric-energy B factories PEP-II at SLAC and KEKB at KEK, respectively. The data samples contain (471±3)×10⁶ BB¯ pairs recorded by the BABAR detector and (772±11)×10⁶ BB¯ pairs recorded by the Belle detector. We measure the CPmore »« less

Measurement of CP Violation in B Anti-B Mixing on the Recoil of Partially Reconstructed Anti-B0 to D* L- Anti-Nu/L Using Kaon Tags

Thesis/Dissertation Gaz, Alessandro

After its formulation in 1960's the Standard Model of Fundamental Interactions has gone through an impressive series of successes, begun with the discovery of neutral weak currents [1] and the experimental observations of the massive carriers of weak interactions, the W^± and Z⁰ bosons [2], [3]. High precision measurements performed at LEP and SLAC test the validity of the theory to an unprecedented level of accuracy and do not show any significant deviations with respect to the Standard Model predictions. One of the attractive features of the Standard Model is the description of the phenomena which violate the matter-antimatter symmetrymore »« less

Measurements of Time-Dependent CP Violation in Radiative B Meson Decays at BABAR

Journal Article Lazzaro, A - AIP Conference Proceedings

We present measurements of the CP-violation parameters S and C for the radiative decays B{sup 0}->pi{sup 0}K{sub S}{sup 0}gamma and B{sup 0}->etaK{sub S}{sup 0}gamma; for B->etaKgamma we also measure the branching fractions and for B{sup +}->etaK{sup +}gamma the time-integrated charge asymmetry A{sub ch}. The data, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represent 467x10{sup 6} BB-bar pairs produced in e{sup +}e{sup -} annihilation at the PEP-II collider. For B{sup 0}->pi{sup 0}K{sub S}{sup 0}gamma we report results in two m(pi{sup 0}K{sub S}{sup 0}) mass regions: S{sub K*(892)g}amma -0.03+-0.29+-0.03, C{sub K*(892)g}amma = -0.14+-0.16+-0.03 for 0.8<m(pi{sup 0}K{sub S}{sup 0})<1.0more »« less

Measurement of the Branching Fraction And Search for Direct CP-Violation in the B+- --> J/Psi Pi+- Decay Mode at BaBar

Technical Report Fobozzi, Francesco

The phenomenon of CP-violation in weak interactions, discovered in 1964 in decays of neutral kaons, receives a simple and elegant explanation in the Standard Model with three generations of quarks. Indeed, in this model the common source of CP-asymmetry phenomena is represented by a simple complex phase in the unitary matrix (the Cabibbo-Kobayashi-Maskawa matrix) describing the charged weak couplings of the quarks. This simple scheme has never received an accurate validation, because the phenomenological parameters determined from measurements of CP-violation in kaons decays are related to the fundamental parameters of the theory in a complex way, sensitive to large theoreticalmore »« less
