  We consider diffractive processes which can be measured at the LHC. Analysis
of diffractive events will give unique information about the high energy
asymptotics of hadron scattering. In semihard diffraction one may study the
partonic structure of the Pomeron. Central Exclusive Diffractive production
provides a possibility to investigate the new particles (Higgs bosons, SUSY
particles,...) in an exceptionally clean environment.
