Study of decays of Ψ(3770) and Ψ(2S) into pp related channels — •Yutie Liang, Martin Galuska, Ingo Heller, Wolfgang Kühn, Jens Sören Lange, Qiang Wang, and Björn Spruck — II. Physikalisches Institut, Universität Gießen

The physics goals of PANDA include a detailed investigation of the spectrum of charmonium. For this physics program, charmonium production cross sections in pp annihilation, which remain poorly measured, are obviously crucial, both to evaluate luminosity requirements and to design detector. With the data of BESIII, we plan to study the decay of Ψ(3770) to pp, which will be very useful to estimate the cross section of pp to Ψ(3770) in the PANDA experiment using detailed balance. The cross section of pp to Ψ(3770) could then be used to provide the lowest limit for the cross section of pp to open charm which is important for the open charm physics in PANDA. We also plan to study decays of Ψ(3770) and Ψ(2S) to ppπ0(η). According to theory studies, knowledge of the decay of charmonium into pp related channels can be used to estimate the numerical scale of the charmonium production cross section with certain theory models. The study of these channels will be helpful for the estimate of associated charmonium production in the PANDA experiment.
