New Physics Search in the LHCb Era (open access)

New Physics Search in the LHCb Era

The authors present theoretical and experimental preparations for an indirect search for new physics (NP) using the rare decay {bar B}{sub d} {yields} {bar K}*{sup 0}{mu}{sup +}{mu}{sup -}. They design new observables with very small theoretical uncertainties and good experimental resolution.

Observation of the Rare Decay B^+ to K^+ \pi^0 \pi^0 (open access)

Observation of the Rare Decay B^+ to K^+ \pi^0 \pi^0

We report an analysis of charmless hadronic decays of charged B mesons to the final state K{sup +}{pi}{sup 0}{pi}{sup 0}, using a data sample of 470.9 {+-} 2.8 million B{bar B} events collected with the BABAR detector at the {Upsilon}(4S) resonance. We observe an excess of signal events with a significance above 10 standard deviations including systematic uncertainties and measure the branching fraction to be {Beta}(B{sup +}{yields}K{sup +}{pi}{sup 0}{pi}{sup 0}) = (15.5 {+-} 1.1 {+-} 1.6) x 10{sup -6}, where the uncertainties are statistical and systematic, respectively.

Searches for Lepton Flavor Violation in the Decays tau+- ---> e+- gamma and tau+- ---> mu+- gamma (open access)

Searches for Lepton Flavor Violation in the Decays tau+- ---> e+- gamma and tau+- ---> mu+- gamma

Searches for lepton-flavor-violating decays of a {tau} lepton to a lighter mass lepton and a photon have been performed with the entire dataset of (963 {+-} 7) x 10{sup 6} {tau} decays collected by the BABAR detector near the {Upsilon}(4S), {Upsilon}(3S) and {Upsilon}(2S) resonances. The searches yield no evidence of signals and they set upper limits on the branching fractions of {Beta}({tau}{sup {+-}} {yields} e{sup {+-}}{gamma}) < 3.3 x 10{sup -8} and {Beta}({tau}{sup {+-}} {yields} {mu}{sup {+-}}{gamma}) < 4.4 x 10{sup -8} at 90% confidence level.

Hot Topics in BaBar

The authors present recent results concerning the searches for light Higgs-like particles in the decay {Upsilon}(3S) {yields} {gamma}A{sup 0},A{sup 0} {yields} {mu}{sup +}{mu}{sup -} as well as for the lepton flavor violation in the decays {Upsilon}(3S) {yields} e{sup {+-}}{tau}{sup {-+}}, {mu}{sup {+-}}{tau}{sup {-+}} and {tau} {yields} 3l (l = e, {mu}) with the BABAR experiment.

Leptonic Decays of the Charged B Meson (open access)

Leptonic Decays of the Charged B Meson

The authors present a search for the decay B{sup +} {yields} {ell}{sup +}{nu}{sub {ell}} ({ell} = {tau}, {mu}, or e) in (458.9 {+-} 5.1) x 10{sup 6} {Upsilon}(4S) decays recorded with the BABAR detector at the SLAC PEP-II B-Factory. A sample of events with one reconstructed exclusive semi-leptonic B decay (B{sup -} {yields} D{sup 0}{ell}{sup -}{bar {nu}}X) is selected, and in the recoil a search for B{sup +} {yields} {ell}{sup +}{nu}{sub {ell}} signal is performed. The {tau} is identified in the following channels: {tau}{sup +} {yields} e{sup +}{nu}{sub e}{bar {nu}}{sub {tau}}, {tau}{sup +} {yields} {mu}{sup +}{nu}{sub {mu}}{bar {nu}}{sub {tau}}, {tau}{sup +} {yields} {pi}{sup +}{bar {nu}}{sub {tau}}, and {tau}{sup +} {yields} {pi}{sup +}{pi}{sup 0}{bar {nu}}{sub {tau}}. The analysis strategy and the statistical procedure is set up for branching fraction extraction or upper limit determination. They determine from the dataset a preliminary measurement of {Beta}(B{sup +} {yields} {tau}{sup +}{nu}{sub {tau}}) = (1.8 {+-} 0.8 {+-} 0.1) x 10{sup -4}, which excludes zero at 2.4{sigma}, and f{sub B} = 255 {+-} 58 MeV. Combination with the hadronically tagged measurement yields {Beta}(B{sup +} {yields} {tau}{sup +}{nu}{sub {tau}}) = (1.8 {+-} 0.6) x 10{sup -4}. They also set preliminary limits on the branching fractions at …

Search for B-meson decays to b1rho and b1K___ (open access)

Search for B-meson decays to b1rho and b1K___

We present a search for decays of B mesons to final states with a b{sub 1} meson and a {rho} or K*(892) meson. The search is based on a data sample consisting of 465 million B{bar B} pairs collected by the BABAR detector at the SLAC National Accelerator Laboratory. We do not observe any statistically significant signal. The upper limits we set on the branching fractions range from 1.4 to 8.0 x 10{sup -6} at the 90% confidence level (C.L.), including systematic uncertainties.
