Light vector meson production in pp collisions at s=7 TeV

Low mass dilepton production in pp, p–Pb and Pb–Pb collisions with ALICE

“…It can be observed that, while the Perugia-0 and Perugia-11 tunes underestimate the cross section by about a factor of two, the other calculations agree with the measurement within 15%. The considerations on the comparison with the models also hold for the previously analyzed data at √ s = 7 TeV [8].…”

“…1 for dimuon p T > 1 GeV/c, was described as a superposition of light meson decays into muon pairs, with an additional contribution coming from charm and beauty semi-muonic decays. Low-mass resonance shapes, as well as the acceptance and efficiency for each process, were obtained through a Monte Carlo simulation with a parametric generator [8], while open charm and beauty were generated using a parametrization of PYTHIA. Alternative fits to the mass spectrum were performed replacing this hadronic cocktail with empirical functions.…”

“…Since no measurement is available at this energy, it was obtained interpolating the results at 2.76 and 7 TeV. For each p T interval, the differential cross section dσ pp /dydp T at 5.02 TeV was interpolated following the assumption that the cross section increases with √ s according to a power law √ s = A · s n , where A and n are determined using the data at 2.76 and 7 TeV [8]. The interpolated cross section, which refers to the rapidity range of −4.0 < y cms < −2.5, was finally scaled to the forward and backward rapidity windows 2.03 < y cms < 3.53 and −4.46 < y cms < −2.96 as used for the analysis of the p-Pb data.…”

ϕ Meson Measurements at RHIC with the PHENIX Detector

“…PHENIX measured the differential cross section of φ meson at forward and backward rapidities in p+p collisions at √ s = 510 GeV [12]. The integrated cross section over the measured p T range, 2.79 ± 0.20 (stat) ± 0.17 (syst) ± 0.34 (norm) ×10 −2 mb, from this measurement and those from PHENIX at √ s = 200 GeV [5] and LHC at √ s = 2.76 and 7.0 TeV [11,[13][14][15] are used to study the energy dependence of φ meson production at forward rapidity, 1.2 < y < 2.2, in p+p collisions, as shown in Fig. 1.…”

Constrains for non-standard statistical models of particle creations by identified hadron multiplicity results at LHC energies

“…In the present paper we would like to use data from the ALICE experiment performed with pp interaction of √ s 7 TeV available energy [3][4][5][6][7][8] to test the particle creation description based on a thermodynamical approach.…”
