TL;DR

This paper calculates the complete supersymmetric next-to-leading order corrections to light Higgs boson production via weak boson fusion, highlighting their significance for precision Higgs sector analysis at the LHC.

Contribution

It provides the first comprehensive calculation of supersymmetric NLO corrections for Higgs production in weak boson fusion, including electroweak and QCD effects.

Findings

Electroweak corrections are comparable to Standard Model NLO corrections.

Supersymmetric QCD corrections are significantly smaller than electroweak corrections.

Higher-order corrections are crucial for precision Higgs sector studies at the LHC.

Abstract

We compute the complete supersymmetric next-to-leading order corrections to the production of a light Higgs boson in weak boson fusion. The size of the electroweak corrections is of similar order as the next-to-leading order corrections in the Standard Model. The supersymmetric QCD corrections turn out to be significantly smaller than their electroweak counterparts. These higher--order corrections are an important ingredient to a precision analysis of the (supersymmetric) Higgs sector at the LHC, either as a known correction factor or as a contribution to the theory error.
