Comprehensive evidence about a narrow $p \overline{p}$ state of mass 2.02 $GeV/c^2$

We report evidence for the existence of a narrow $p\overline{p}$ state with a mass of 2.02 GeV/c$^2$ and a width below 10 MeV/c$^2$ produced in $\pi^+p(\pi^-p)$ interactions at 20(12) GeV/c in six final states, proceeding via baryon exchange mechanism, that could be interpreted as a $baryonium$ cand...
