متن يادداشت

© CERN for the benefit of the ATLAS collaboration. Ameasurement is presented of the φ×BR(φ → K⁺K⁻) production cross section at √s = 7 TeV using pp collision data corresponding to an integrated luminosity of 383 μb^-1, collected with theATLAS experiment at the LHC. Selection of φ(1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. The differential cross section ismeasured as a function of the transverse momentum, pT,φ , and rapidity, yφ, of the φ(1020) meson in the fiducial region 500< pT,φ <1200MeV, |yφ| < 0.8, kaon pT,K > 230 MeV and kaon momentum pK < 800 MeV. The integrated φ(1020)-meson production cross section in this fiducial range is measured to be σφ×BR(φ → K⁺K⁻) = 570 ± 8 (stat) ± 66 (syst) ± 20 (lumi) μb.
