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