Measurement of the Top Quark Pair Production Charge Asymmetry in Proton-Proton Collisions at √s̅ = 7 TeV Using the ATLAS Detector
(Springer, 2014-02-25)
This paper presents a measurement of the top quark pair (tt̅) production charge asymmetry A_C using 4.7 fb−1 of proton-proton collisions at a centre-of-mass energy √s̅ = 7 TeV collected by the ATLAS detector at the LHC. A ...
Precision Measurement of the B→X_sγ Photon Energy Spectrum, Branching Fraction, and Direct CP Asymmetry A_{CP}(B→X_{s+d}γ)
(American Physical Society, 2012-11-09)
The photon spectrum in the inclusive electromagnetic radiative decays of the B meson, B→X_sγ plus B→X_dγ, is studied using a data sample of (382.8 ± 4.2)×10⁶Υ(4S) →BB̄ decays collected by the BABAR experiment at SLAC. ...
Measurement of the Absolute Branching Fraction for Λ_c⁺ → Λe⁺ν_e
(Amer Physical Soc, 2015-11-25)
We report the first measurement of the absolute branching fraction for Λ_c⁺. This measurement is based on 567 pb⁻¹ of e⁺e⁻ annihilation data produced at √s = 4.599 GeV, which is just above the Λ_c⁺ Λ̅_c̅ threshold. The ...
Measurement of Distributions Sensitive to the Underlying Event in Inclusive Z-Boson Production in pp Collisions at √s = 7 TeV with the ATLAS Detector
(Springer New York LLC, 2014-12-10)
A measurement of charged-particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z-boson, decaying to an electron or muon pair. The measurement ...
Search for B⁺→ K⁺τ⁺τ⁻ at the Babar Experiment
(American Physical Society, 2018-08-24)
We search for the rare flavor-changing neutral current process B⁺→ K⁺τ⁺τ⁻ using data from the BABAR experiment. The data sample, collected at the center-of-mass energy of the Υ(4S) resonance, corresponds to a total integrated ...
Study of η(1475) and Χ(1835) in Radiative J/ψ Decays to γφ
The decay J/ψ → γγφ is studied using a sample of 1.31 x 10⁹ J/ψ events collected with the BESIII detector. Two structures around 1475 MeV/c² and 1835 MeV/c² are observed in the γφ invariant mass spectrum for the first time. ...
Study of High-Multiplicity Three-Prong and Five-Prong τ Decays at BABAR
(Amer Physical Soc, 2012-11-27)
We present measurements of the branching fractions of three-prong and five-prong τ decay modes using a sample of 430million τ lepton pairs, corresponding to an integrated luminosity of 468fb -1, collected with the BABAR ...
Measurement of the Production of a W Boson in Association with a Charm Quark in pp Collisions at √s=7 TeV with the ATLAS Detector
(Springer, 2014-05-16)
The production of a W boson in association with a single charm quark is studied using 4.6 fb⁻¹ of pp collision data at√s = 7 TeV collected with the ATLAS detector at the Large Hadron Collider. In events in which a W boson ...
Search for the Standard Model Higgs Boson Decay to μ⁺μ⁻ with the ATLAS Detector
(Elsevier Science B. V., 2014-11-10)
A search is reported for Higgs boson decay to μ⁺μ⁻ using data with an integrated luminosity of 24.8 fb⁻¹ collected with the ATLAS detector in pp collisions at √s̅ = 7 and 8 TeV at the CERN Large Hadron Collider. The observed ...
Observation of e⁺e⁻ → ωχ_{c1, 2} near √s̅ = 4.42 and 4.6 GeV
