$\gamma \gamma \rightarrow \ell^{+} \ell^{-}$ 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...
