Interpretation ofρ0−ω0Coherence inp¯pAnnihilation

It is noted that the quark-rearrangement model provides a simple explanation of both the coherence and phase of the ${\rho }^0$ and ${\omega }^0$ amplitudes as observed in the ${\rho }^0{\pi }^{+}{\pi }^{-}$ and ${\omega }^0{\pi }^{+}{\pi }^{-}$ final states of low-energy $\overline{p}p$ annihilation.
