    • Measurement of the Muon Reconstruction Performance of the ATLAS Detector using 2011 and 2012 LHC Proton−Proton Collision Data 

      Aad, G.; Abbott, B.; Abdallah, J.; Abdel Khalek, S.; Abdinov, O.; Aben, R.; Abi, B.; Izen, Joseph M.; Leyton, Michael; Lou, Xinchou; Namasivayam, Harisankar; Reeves, Kendall; ATLAS Collaboration (Springer New York LLC, 2014-11-26)
      This paper presents the performance of the ATLAS muon reconstruction during the LHC run with pp collisions at √s = 7 -8 TeV in 2011-2012, focusing mainly on data collected in 2012. Measurements of the reconstruction ...
    • Search for the weak decays J/ψ → D{_s^{(*)⁻} e⁺ ν_e + c.c. 

      Ablikim, M.; Achasov, M. N.; Ai, X. C.; Albayrak, O.; Albrecht, M.; Ambrose, D. J.; Amoroso, A.; Lou, Xinchou; BESIII Collaboration (2014-12-23)
      Using a sample of 2.25 x 10⁸ J/ψ events collected with the BESIII detector at the BEPCII collider, we search for the J/ψ semileptonic weak decay J/ψ → D(s)⁻ e⁺ν(e) + c.c with a much higher sensitivity than previous searches. ...
    • Study of B^{±,0} → J/ψK⁺K⁻K^{±,0} and search for B⁰ → J/ψϕ at BaBar 

      Lees, J. P.; Poireau, V.; Tisserand, V.; Grauges, E.; Palano, A.; Eigen, G.; Stugu, B.; Izen, Joseph M.; Lou, Xinchou; BaBar Collaboration (American Physical Society, 2015-01-07)
      We study the rare B meson decays B^{±,0} → J/ψK⁺K⁻K^{±,0}, B^{±,0} → J/ψϕK^{±,0} and search for B⁰ → J/ψϕ, using 469 x 10⁶ BB̅ events collected at the ϒ(4S) resonance with the BABAR detector at the PEP-II e⁺e⁻ asymmetric ...
