Momentum conservation and correlation analyses in heavy-ion collisions at ultrarelativistic energies

Abstract

Global transverse-momentum conservation induces correlations between any number of particles, which contribute in particular to the two- and three-particle correlations measured in heavy-ion collisions. These correlations are examined in detail, and their importance for studies of jets and their interaction with the medium is discussed.
