Findings

Potential to significantly improve sensitivity to anomalous couplings.

Feasibility of measurement with only 10 pb$^{-1}$ of data.

Enhanced constraints compared to previous LEP results.

Abstract

We report on a possible measurement at the LHC using the first data and a luminosity of 10 pb$^{-1}$ of $W$ and $Z$ pair production via two-photon exchange. This measurement allows to increase the present sensitivity on $WW\gamma \gamma$ and $ZZ\gamma \gamma$ quartic anomalous couplings from the LEP experiments by almost three orders of magnitude.
