Measurements of cross sections of inelastic and diffractive processes in proton–proton collisions at LHC energies were carried out with the ALICE detector. The fractions of diffractive processes in inelastic collisions were determined from a study of gaps in charged particle pseudora-pidity distributions: for single diffraction (diffractive mass
Differential cross sections of charged particles in inelastic pp collisions as a function of p T have been measured at √ s = 0.9, 2.76 and 7 TeV at the LHC. The p T spectra are compared to NLO-pQCD calculations. Though the differential cross section for an individual √ s cannot be described by NLO-pQCD, the relative increase of cross section with √ s is in(More)
The ALICE Collaboration at the LHC has measured the J/ψ and ψ photoproduction at mid-rapidity in ultra-peripheral Pb–Pb collisions at √ s NN = 2.76 TeV. The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of(More)
