TL;DR

This paper calculates the complete next-to-leading order electroweak corrections to Higgs boson production via gluon fusion with a focus on differential distributions and the impact of different renormalization schemes.

Contribution

It provides the first detailed calculation of electroweak corrections to Higgs+jet production in gluon fusion, highlighting scheme dependence and transverse momentum effects.

Findings

Electroweak corrections are about 4.3% in the G_mu scheme.

Discrepancies between schemes are reduced after including electroweak corrections.

Electroweak corrections strongly depend on Higgs transverse momentum.

Abstract

We present the calculation of complete next-to-leading order electroweak corrections to the Higgs boson production in $gg\to g H$ channel. We apply the method of differential equations combined with the selection of optimized master integrals to accomplish the calculation of master integrals. We consider three distinct renormalization schemes. At leading order, the differential distributions and the total cross section show a strong dependence on the renormalization scheme. However, these discrepancies are considerably suppressed once electroweak corrections are taken into account. For $G_\mu$ scheme, the electroweak correction amounts to approximately $4.3\%$ of the total cross section. Importantly, we find that the EW corrections exhibit a strong dependence on Higgs transverse momentum.
