# Precision diboson measurements at hadron colliders

## TL;DR

This paper explores advanced methods for measuring anomalous triple gauge couplings at the LHC, focusing on operators that are difficult to detect due to suppressed interference, and assesses future collider prospects using exclusive variables and NLO QCD effects.

## Contribution

It introduces a novel approach to measure suppressed anomalous couplings at the LHC by employing exclusive variables sensitive to interference effects and includes NLO QCD corrections in the analysis.

## Key findings

- Enhanced sensitivity to ${
m O}_{3W}$ and ${
m O}_{3 ilde W}$ operators using exclusive variables.
- Projected improvements in measurement precision at HL-LHC and HE-LHC.
- Identification of strategies to overcome flat directions in Wilson coefficient space.

## Abstract

We discuss the measurements of the anomalous triple gauge couplings at Large Hadron Collider focusing on the contribution of the ${\cal O}_{3W}$ and ${\cal O}_{3\tilde W}$ operators. These deviations were known to be particularly hard to measure due to their suppressed interference with the SM amplitudes in the inclusive processes, leading to approximate flat directions in the space of these Wilson coefficients. We present the prospects for the measurements of these interactions at HL-LHC and HE-LHC using exclusive variables sensitive to the interference terms and taking carefully into account effects appearing due to NLO QCD corrections.
