How to measure the pion structure function at HERA
Abstract
We suggest a method of determination of the pion structure function down to x 10-4 based on semi-exclusive deep inelastic scattering off protons. The idea is to exploit the nonperturbative π N$ and π Fock components of the nucleon, which contribute significantly to deep inelastic scattering and dominate the fragmentation of protons into fast neutrons and deltas. The intrinsic factorization properties of the semi-exclusive cross section give a good test for the validity of this approach.
