Résumé : | Charged-hadron transverse-momentum and pseudorapidity distributions in proton-proton collisions at √s=7TeV are measured with the inner tracking system of the CMS detector at the LHC. The charged-hadron yield is obtained by counting the number of reconstructed hits, hit pairs, and fully reconstructed charged-particle tracks. The combination of the three methods gives a charged-particle multiplicity per unit of pseudorapidity dNch/ dη |
