Comment on "Protonium annihilation into $\pi^{0} \pi^{0}$ at rest in a liquid hydrogen target"

We comment on the recent paper published by the Obelix Collaboration on protonium annihilation into pi /sup 0/ pi /sup 0/ at rest in a liquid hydrogen target ÝPhys. Rev. D 65, 012001 (2002)¿, with particular reference to the discrepancy with the results obtained by the Crystal Barrel Collaboration....
