# Non-standard Higgs couplings in single Higgs boson production at the LHC and future linear collider

## TL;DR

This paper explores how single Higgs boson production at the LHC and future linear colliders can be used to detect non-standard Higgs couplings, providing sensitivity bounds through a model-independent analysis.

## Contribution

It introduces a comprehensive analysis of non-standard HZgamma and Hgammagamma couplings in single Higgs production at colliders, including new sensitivity bounds.

## Key findings

- Sensitivity bounds on non-standard Higgs couplings established
- Analysis covers LHC semi-elastic and linear collider gamma-e processes
- Model-independent approach enhances applicability of results

## Abstract

We investigate the potential of single Higgs boson production at the LHC and at egamma mode of future linear electron-positron collider to probe non-standard HZgamma and Hgammagamma couplings. We consider the semi-elastic production process pp-> p gamma p-> pHqX at the LHC where q represents the quarks and X represents the remnants of one of the initial protons. We also study the single Higgs production through gamma e-> He in the egamma collision at the future linear collider. We perform a model-independent analysis and obtain the sensitivity bounds on the non-standard Higgs couplings for both colliders.
