Abstract

We prove a new soft-pion theorem for the near-threshold pion production by a hard electromagnetic probe. This theorem relates various near-threshold pion-production amplitudes to the nucleon distribution amplitudes. The new soft-pion theorem is in good agreement with the SLAC data for the structure function F₂^p(W, Q²) for W2≤1.4 GeV2 and 9≤Q²≤30.7 GeV².
