CMS results on exclusive production

A search for exclusive or quasi-exclusive $\gamma\gamma \rightarrow W^{+}W^{-}$ production, ${\rm pp} \rightarrow {\rm p}^{(*)} W^{+}W^{-} {\rm p}^{(*)} \rightarrow {\rm p}^{(*)} \mu^{\pm} {\rm e}^{\mp} {\rm p}^{(*)}$, at $\sqrt{s}$ = 8 TeV (7 TeV) are reported using data corresponding to an integrated luminosity of 19.7 $\rm {fb}^{-1}$ (5.5$\rm {fb}^{-1}$), respectively. In this study, we look for any deviations that there might be from the Standard Model, and the results are used to set limits on the Anomalous Quartic Gauge Couplings. We also report a measurement of the exclusive production of pairs of charged pions in proton-proton collisions. The differential cross sections for $\pi^{+}\pi^{-}$ pairs as a function of the pion pair invariant mass is measured and compared to several phenomenological predictions.
