Hadronic resonance production with the ALICE experiment in pp and Pb-Pb collisions at LHC energies

Abstract

Hadronic resonances ${\mathrm{K}}^{\ast }(892{)}^0$, $\varphi$(1020) and $\Sigma (1385{)}^{\pm }$ have been measured by the ALICE experiment in pp collisions at $\sqrt{s}=7$ TeV and in Pb-Pb collisions at $\sqrt{s_{{}_{\mathrm{NN}}}}=2.76$ TeV. Transverse momentum spectra, particle ratios, nuclear modification factor and comparison with model predictions are discussed. In addition, ALICE results are compared with data obtained at RHIC energy.
