Measurement of exclusive $\gamma \gamma \to {\ell }^{+}{\ell }^{-}$ production in proton-proton collisions at $\sqrt{s}=7$ TeV with the ATLAS detector

ATLAS Collaboration

This Letter reports a measurement of the exclusive $\gamma \gamma \to {\ell }^{+}{\ell }^{-}(\ell =e,\mu )$ cross-section in proton-proton collisions at a centre-of-mass energy of 7 TeV by the ATL…
