# Weak Boson Fusion at 100 TeV

## TL;DR

This paper evaluates the potential of a 100 TeV hadron collider for precision Higgs measurements via weak-boson-fusion, demonstrating its sensitivity to rare Higgs properties with appropriate detector and trigger strategies.

## Contribution

It provides a comprehensive analysis of weak-boson-fusion kinematics and proposes a two-step jet veto, highlighting the collider's sensitivity to rare Higgs decay modes and couplings.

## Key findings

- Sensitivity to invisible Higgs branching ratio of 0.5%
- Detection of second-generation muon Yukawa coupling at 2%
- Ability to measure Higgs total width around 5%

## Abstract

From the LHC runs we know that, with increasing collider energy, weak-boson-fusion Higgs production dominates as an environment for precision measurements. We show how a future hadron collider performs for three challenging benchmark signatures. Because all of these measurements rely on the tagging jet signature, we first give a comprehensive analysis of weak-boson-fusion kinematics and a proposed two-step jet veto at a 100 TeV hadron collider. We then find this machine to be sensitive to invisible Higgs branching ratios of 0.5%, a second-generation muon Yukawa coupling of 2%, and an enhanced total Higgs width of around 5%, the latter with essentially no model dependence. This kind of performance crucially relies on a sufficient detector coverage and a dedicated weak-boson-fusion trigger channel.
