Abstract

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→e+e- 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→π+π-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.
