Description
In this talk, I will report on the lattice QCD calculation of pion electroproduction on the nucleon. This process describes how pions are produced when nucleons are struck by electrons and provides insights into the internal structure of nucleon. At pion-production threshold, we extract the multipole amplitudes $E_{0+} $ and $L_{0+} $ from the $N+\gamma^*\to N\pi$ matrix element. The rescattering effects between the nucleon and the pion are also evaluated, and the Lellouch-Luscher factor is properly included to convert the $N\pi$ state in the finite volume to that in the infinite volume. processes involving pions.
