  When a jet collides coherently with many parton scatterers at very high
energies, the Bose-Einstein symmetry with respect to the interchange of the
virtual bosons leads to a destructive interference of the Feynman amplitudes in
most regions of the momentum transfer phase space but a constructive
interference in some other regions of the momentum transfer phase space. As a
consequence, the recoiling scatterers have a tendency to come out collectively
along the incident jet direction, each carrying a substantial fraction of the
incident jet longitudinal momentum. The manifestation of the Bose-Einstein
interference as collective recoils of the scatterers along the jet direction
may have been observed in angular correlations of hadrons associated with a
high-pT trigger in high-energy heavy-nuclei collisions at RHIC and LHC.
