Measuring the Higgs-bottom coupling in weak boson fusion

TL;DR

This paper proposes a novel method combining jet substructure and matrix element techniques to measure the Higgs-bottom coupling via weak boson fusion, overcoming previous analysis limitations.

Contribution

It introduces a new approach to probe the bottom-Yukawa interaction in boosted Higgs production, improving sensitivity over traditional cut-and-count methods.

Findings

Higgs-bottom coupling can be constrained to 0.82-1.14 times the Standard Model value with 600 fb^{-1} data.

Combining jet substructure and matrix element methods enhances measurement sensitivity.

The approach mitigates previous 'no-go' results in this channel.

Abstract

We study Higgs production through weak boson fusion with subsequent decay to bottom quarks. By combining jet substructure techniques and matrix element methods in different limits we motivate this channel as a probe of the bottom-Yukawa interactions in the boosted regime. In particular we ameliorate the "no-go" results of cut-and-count analyses in this channel. After applying a data-driven reconstruction approach we find that the Higgs-bottom coupling can be limited to $0.82 < y_b/y_b^{\text{SM}} <1.14$ with $600~\mathrm{fb}^{-1}$.
