Direct determination of two-pion correlations for $\overline{p}p \to 2\pi^{+}2\pi^{-}$ annihilation at rest

We study $\pi\pi$ correlations in the exclusive reaction $\ppb \to 2\pi^+2\pi^-$ at rest measured by the CPLEAR experiment. Avoiding the introduction of an arbitrary reference sample, we analyse differential distributions for equal charge pion pairs removing the phase-space factor event by event. A...
