B. Singh et al. (PANDA collaboration)
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.
