Abstract

We give new experimental results on

\frac{ρ}{ω}

interference and two-body cross sections in

\bar{p} p

annihilation at

2.3 \frac{GeV}{c}

. These are used, together with

\frac{ρ}{ω}

interference results from lower energies, to argue that the annihilation process is not mediated by discrete

s

-channel mesonic resonances in the mass range 2.1-2.6 GeV.
