Anomalous WW $\gamma$ coupling in photon-induced processes using forward detectors at the LHC

TL;DR

This paper proposes a new method to test the Standard Model at the LHC by analyzing photon-induced WW production with forward detectors, significantly improving sensitivity to anomalous WWγ couplings.

Contribution

It introduces a novel approach combining main detector and forward proton measurements to enhance sensitivity to anomalous gauge couplings at the LHC.

Findings

Sensitivity to anomalous WWγ coupling improved by over 5 times compared to LEP.

Sensitivity improved by over 30 times compared to Tevatron.

Method leverages photon-induced processes and forward detectors for precise measurements.

Abstract

We present a new method to test the Standard Model expectations at the LHC using photon-induced $WW$ production. Both $W$ decay in the main ATLAS or CMS detectors while scattered protons are measured in forward detectors. The sensitivity to anomalous $WW\gamma$ triple gauge coupling can be improved by more than a factor 5 or 30 compared to the present LEP or Tevatron sensitivity respectively.
