abstract = "A measurement is presented of the phi x BR(phi - GT K+ K-) production cross section at root s = 7 TeV using pp collision data corresponding to an integrated luminosity of 383 mu b(-1), collected with the ATLAS experiment at the LHC. Selection of phi(1020) mesons is based on the identification of charged kaons by their energy loss in the pixel detector. The differential cross section is measured as a function of the transverse momentum, pT, phi, and rapidity, y(phi), of the phi(1020) meson in the fiducial region 500 LT pT,phi LT 1200MeV, vertical bar y phi| LT 0.8, kaon p(T), (K) GT 230 MeV and kaon momentum p(K) LT 800 MeV. The integrated phi(1020)-meson production cross section in this fiducial range is measured to be sigma(phi) x BR(phi - GT K+ K-) = 570 +/- 8 (stat) +/- 66 (syst) +/- 20 (lumi) mu b.",
