## Abstract

GPDs provide a 3D picture of the nucleon, and the hard exclusive pion production have been providing important inputs for understanding the chiral-odd GPDs. The Jefferson Lab Hall A experiment E12-06-014 extended the kinematic coverage in the quark valence regime, and has measured the cross section of exclusive $\pi^0$ production off protons at large values of $x_B$ (0.36, 0.48, and 0.60) and $Q^2$ (3.1 to 8.4 GeV 2 ). The results of the E12-06-014 measurement will be presented in this talk.
