QCD factorization theorems for DIS exclusive processes and inclusive diffraction: New probes of hadrons and nuclei

We review applications of the QCD factorization theorems for diffractive DI S processes. We argue that DIS exclusive processes provide a number of effe ctive ways of probing light-cone mason wave functions, and comparing wave f unctions of various baryons. Connection between the factorization theorem f or hard inclusive diffraction processes in DIS and phenomenon of nuclear sh adowing is explained. Strong nuclear shadowing is predicted as well as exis tence of high energy color transparency at x similar to 10(-2) followed by the color opacity for x less than or equal to 10(-3).
