Description
Exclusive meson electroproduction experiments allow for the study of baryon structure. Investigating nucleons at this scale probes the fundamental structure of the universe. When an incoming electron interacts with a target proton, it interacts via a virtual photon. The virtual photon can excite the proton to a nucleon resonance, N*. The resonance region typically corresponds to an invariant mass, W, range of about 1 to 2.5 GeV. While the low invariant mass range is dominated by the single-pion production channel, the double-pion channel dominates the higher invariant mass range. The goal of this research is to extract cross sections in the resonance region through analysis of double-pion production extracted from an electron-proton scattering experiment, which also demands a comprehensive simulation of the double-pion reaction channel under the same kinematics. This analysis covers a W range [1.40, 2.45] GeV and Q² range [2.0, 11.0] GeV² acquired with an electron beam above 10 GeV for the Run Group A datasets collected with the CLAS12 detector in Hall B at Thomas Jefferson National Accelerator Facility (JLab).
