The exclusive charmonium production process in pp¯ annihilation with an associated π0 meson pp¯ →J=ψπ0 is studied in the framework of QCD collinear factorization. The feasibility of measuring this reaction through the J=ψ → eþe− decay channel with the AntiProton ANnihilation at DArmstadt (PANDA ¯ ) experiment is investigated. Simulations on signal reconstruction efficiency as well as the background rejection from various sources including the pp¯ → πþπ−π0 and pp¯ → J=ψπ0π0 reactions are performed with PANDAROOT, the simulation 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.
