Abstract:
The exclusive charmonium production process in pp
̄ annihilation with an associated π 0 meson pp
̄ → J/ψπ 0
is studied in the framework of QCD collinear factorization. The feasibility of measuring this reaction through
the J/ψ → e+ e− decay channel with the PANDA (AntiProton ANnihilation at DArmstadt) experiment is in-
vestigated. Simulations on signal reconstruction efficiency as well as the background rejection from various
sources including the pp
̄ → π + π −π 0 and pp
̄ → J/ψπ 0 π 0 reactions are performed with PandaRoot, the simula-
tion and analysis software framework of the PANDA experiment. It is shown that the measurement can be done
at PANDA with significant constraining power under the assumption of an integrated luminosity attainable in
four to five months of data taking at the maximum design luminosity.
