    abstract = "We study pi pi correlations in the exclusive reaction (p) over bar p –>
2 pi(+)2 pi(-)pi(0) at rest with complete reconstruction of the
kinematics for each event. Inclusive and differential distributions
properly normalized show an enhancement for small invariant masses
M++,M– of like-pion pairs. An even stronger enhancement is seen for the
double differential distributions for low pion-pair masses. The signal
is strongest when the pi(0) energy is large and much weaker when this
energy is small. Dynamical models with resonances in the final state are
confronted with the data. For the kinematic situation where the rho 3 pi
channel is important the simulation predicts a large pion correlation
for the double differential density, qualitatively explaining the
observed bahaviour. The stochastic HBT mechanism is not supported by
these findings for the exclusive annihilation reaction studied."
