Probing hadron structure by high energy scattering processes

Protons and neutrons are known to be the building blocks of matter, and also known to be the bound states of quarks and gluons - the partons, whose dynamics is best described by Quantum Chromodynamics (QCD). QCD has been very successful in interpreting and predicting high-energy scattering processes and in extracting the information on short-distance QCD dynamics. In this talk, I will review the progress in probing hadron structure by using high energy scattering processes. In addition to probing parton momentum and helicity distribution functions, I will discuss possibilities and progresses to probe parton's transverse motion and multiparton quantum correlations inside a hadron by using various QCD high energy scattering processes.
