A new hard QCD phenomenon - proton diffraction into three jets

Abstract

We argue that the process of the proton diffraction into three jets in proton-nucleus scattering at LHC will allow to investigate the light-cone wave function of protons, generalized gluon densities in nuclei at small x, as well as the interplay of the color transparency and opacity phenomena.
