Abstract

Recent measurements are discussed of inclusive and exclusive diffractive processes in pp collisions at √ s = 7 TeV at the LHC using the CMS detector. Results are presented of the singleand double-diffractive cross section and of the inclusive differential cross section for events with a forward rapidity gap. A study of exclusiveW +W− production by two-photon exchange, where, in different kinematic regions, both confirmation and deviations from the Standard Model predictions are searched, is reported. Finally, a joint measurement with the CMS and TOTEM detectors of the pseudorapidity distribution of charged particles produced in pp collisions at √ s= 8 TeV is presented. This is the first joint study between the two experiments.
