TL;DR
This paper presents a phenomenological analysis of CLAS data on double charge pion electroproduction, focusing on isobar channels and electrocouplings at low Q², providing insights into nucleon resonance contributions.
Contribution
It introduces a new analysis of CLAS 2π electroproduction data, extracting electrocouplings and isobar contributions in a specific Q² range, advancing understanding of nucleon resonances.
Findings
Determined electrocouplings for $P_{11}(1440)$ and $D_{13}(1520)$.
Analyzed contributions from isobar channels.
Provided detailed differential and integrated cross sections.
Abstract
Recent developments in phenomenological analysis of the CLAS data on 2 electroproduction are presented. The contributions from isobar channels and , electrocouplings at from 0.25 to 0.6 GeV were determined from the analysis of comprehensive data on differential and fully integrated 2 cross sections. Experiment Numbers: E94-005 Group: Hall B
