Description

Proton anti-proton production has been used to search for possible intermediate systems in various experiments. Evidence for a potential narrow resonance in the ppbar system is scarce, while there is no evidence for a wide resonance in the ppbar system in either photoproduction or electroproduction.
Previous high statistic photoproduction analyses have focused on the extraction of cross-sections and have found no evidence of a potential narrow resonance; the production mechanism of the ppbar still remains unclear. In this work, we use Run Group A data from the CLAS12 collaboration at beam energies of 10.2GeV and 10.6GeV to perform the first high statistic electroproduction analysis of ppbar. Basic data features and preliminary analysis results will be presented.
