Experiment: e1-6a run CLAS data, 2012

Spokespersons: P. Khetarpal, P. Stoler, I. Aznauryan, V. Kubarovsky,

Experiment comment: These measurements allow us to access the dominant pion-nucleon s-wave multipoles $E_{0+}$ and $S_{0+}$ in the near-threshold region. In the light-cone sum-rule framework (LCSR), these multipoles are related to the generalized form factors $G_1^{\pi^0 p}(Q^2)$ and $G_2^{\pi^0 p}(Q^2)$.
