Novel Bose-Einstein Interference Effects
in the Passage
of a Jet in a Dense Medium, C. Y. Wong; Oak
Ridge National Laboratory, U.S.A. − 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 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 [1]. 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 AuAu collisions at
RHIC [2,3].
