Annotation
Evaluation of fully integrated double pion electroproduction cross sections of protons was carried out at $1.4<W<2.0 GeV$, $5<Q^2<12 GeV^2$. The cross-section evaluation was obtained from an approach based on extrapolation of the double pion component of inclusive structure functions $F_1$ and $F_2$ from photon virtualities $Q^2<5 GeV^2$ towards $5<Q^2<12 GeV^2$. $Q^2$-parameterization compatible with restrictions from the Operator Product Expansion was used to conduct the extrapolation. The results will be used to extract double pion electroproduction cross sections of protons in future experiments with the new CLAS12 detector.
