Light vector meson production in pp collisions at sqrt(s) = 7 TeV
Original language description
The ALICE experiment has measured low-mass dimuon production in pp collisions at sqrt{s} = 7 TeV in the dimuon rapidity region 2.5<y<4. The observed dimuon mass spectrum is described as a superposition of resonance decays (eta, rho, omega, eta^{'},phi) into muons and semi-leptonic decays of charmed mesons. The measured production cross sections for omega and phi are sigma_omega (1<p_t<5 GeV/c,2.5<y<4) = 5.28 +- 0.54 (stat) +- 0.50 (syst) mb and sigma_phi(1<p_t<5 GeV/c,2.5<y<4)=0.940 +- 0.084 (stat) +- 0.078 (syst) mb. The differential cross sections d^2sigma/dy dp_t are extracted as a function of p_t for omega and phi. The ratio between the rho and omega cross section is obtained. Results for the phi are compared with other measurements at the same energy and with predictions by models.
