$\gamma \gamma \rightarrow \ell^{+} \ell^{-}$ and $\gamma p \rightarrow \Upsilon p \rightarrow \ell^{+} \ell^{-} p$ at CMS

Exclusive dilepton events are characterized by the presence of two back-to-back leptons, and no other detector activity above threshold. In $pp$ collisions in the CMS experiment, this signature can result from two-photon interactions ($\gamma \gamma \rightarrow \ell^{+}\ell^{-}$) or $\Upsilon$ photo...

description Exclusive dilepton events are characterized by the presence of two back-to-back leptons, and no other detector activity above threshold. In $pp$ collisions in the CMS experiment, this signature can result from two-photon interactions ($\gamma \gamma \rightarrow \ell^{+}\ell^{-}$) or $\Upsilon$ photoproduction ($\gamma p \rightarrow \Upsilon p \rightarrow \ell^{+} \ell^{-} p$). In the early data from the LHC, these events will provide a calibration sample for luminosity and lepton reconstruction studies, and allow studies of diffraction and QCD.
