The PANDA detector will allow to investigate the charmonium region in [Formula: see text] annihilation processes at a energy range for which production cross sections of charmonium states are unknown, in particular for those above the [Formula: see text] threshold. Cross sections for these states are expected to be rather small, so that it has to be verified that PANDA can cope with small rates. Therefore, several reaction channels have been identified as "benchmark channels" and the PANDA performance has been investigated in Monte Carlo studies. The focus of the charmed benchmark channels is to show the physics performance of the planned apparatus and to investigate the feasibility of separating the physics signal from a huge hadronic background.

Abstract A self-consistent data set, with all the necessary inputs for Monte Carlo simulations of electron transport through gaseous tetrahydrofuran (THF) in the energy range 1–100 eV, has been critically compiled in this study. Accurate measurements of total electron scattering cross sections (TCSs) from THF have been obtained, and considered as reference values to validate the self-consistency of the proposed data set. Monte Carlo simulations of the magnetically confined electron transport through a gas cell containing THF for different beam energies (3, 10 and 70 eV) and pressures (2.5 and 5.0 mTorr) have also been performed by using a novel code developed in Madrid. In order to probe the accuracy of the proposed data set, the simulated results have been compared with the corresponding experimental data, the latter obtained with the same experimental configuration where the TCSs have been measured.
