Exclusive processes in proton-proton collisions with the CMS experiment at the LHC

Abstract

We present the recent measurements of exclusive processes performed in the CMS experiment at the LHC using data collected at a centre of mass energy of 7 TeV. These measurements include the double-pomeron production of photon pairs, the two-photon production of leptons pairs, and the previously undetected two-photon production of W boson pairs. While in case of the two first processes that enables to set limits on production cross-section, in the later case it provides also stringent limits on the anomalous quartic gauge couplings.Comment: Presented at the Low x workshop, May 30 - June 4 2013, Rehovot and Eilat, Israe
