Abstract:
Production of heavy photons (Drell-Yan), gauge bosons, Higgs bosons, heavy
flavors, which is treated within the QCD parton model as a result of hard parton-parton collision, can be considered as a bremsstrahlung process in the target rest frame. In my talk, I discuss the basic features of the diffractive channels of these processes in the framework of color dipole approach. The main observation is a dramatic breakdown of diffractive QCD
factorisation due to the interplay between soft and hard interactions, which dominates these processes.
