We report the first measurement at the LHC of coherent photoproduction of ρ0 mesons in ultra-peripheral Pb-Pb collisions. The invariant mass and transverse momentum distributions for ρ0 production are studied in the π+π− ...

We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at sNN−−−√=2.76sNN=2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high-pT) ...
