Abstract: (Springer)

In the study of the annihilation

\bar pp \to K\bar K\pi \pi \pi

at rest, we observed an important enhancement in the

\left( {K\bar K\pi } \right)

neutral system. We show that this enhancement is the manifestation of a resonance, which we call the E0 meson, with quantum numbersM=(1425±7) MeV, Γ=(80±10) MeV,IGJP=0+0− and branching ratio

E \to K*\bar K\left( {\bar K*K} \right)/E \to \left( {K\bar K} \right)\pi- 1
