Charged Two-Pion Electroproduction in the Resonance Region with CLAS12

Studying the nucleon resonance (N*) structure is crucial for understanding the strong interaction dynamics that drive baryon formation from quarks and gluons. Jefferson Lab's CLAS detector in Hall B has already provided the majority of the world’s data on charged double-pion electroproduction in the nucleon resonance region for photon virtualities (Q²) up to 5 GeV², enabling the determination of resonance electroexcitation amplitudes for most N* in the mass range up to 1.8 GeV. As the only detector in the world capable of exploring resonance electroexcitation amplitudes in the largely uncharted range of Q² > 5.0 GeV², CLAS12 offers a unique opportunity to study the evolution of resonance structure at the distances where the transition from strongly coupled to perturbative QCD regimes is expected. The charged double-pion channel is particularly valuable for the studies of N* in the mass range > 1.6 GeV which decay preferentially to the Npi+pi- final states. This presentation will highlight the preliminary double-pion channel cross-sections results in the resonance region and the methodology used to extract them, based on one of the first measurements utilizing the CLAS12 detector.
