Electroweak loop corrections to $gg\to gH$ at the LHC

TL;DR

This paper calculates the complete electroweak loop corrections to the Higgs production process with a jet at the LHC, revealing significant shape distortions in the Higgs transverse momentum distribution.

Contribution

It provides the first full electroweak correction results for the $gg o gH$ process, essential for precise Higgs + jet predictions at the LHC.

Findings

Electroweak corrections increase total cross section by about 4%.

Corrections vary with Higgs transverse momentum, exceeding 4% at low and dropping below -4% at high.

Results are crucial for next-to-leading order electroweak accuracy in Higgs + jet studies.

Abstract

We present the results of the complete electroweak loop corrections to the process $ gg \to gH $ at the Large Hadron Collider. The electroweak corrections to the total cross section are found to be approximately $ +4\% $. At the differential level, the corrections exceed $ +4\% $ in the low Higgs transverse momentum region and fall below $ -4\% $ in the high transverse momentum region, leading to a noticeable shape distortion for this distribution. Our results represent a necessary step towards to complete next-to-leading order electroweak correction of the Higgs + jet process.
