TL;DR

This paper calculates the next-to-leading order electroweak corrections to Higgs production with bottom quark pairs at the LHC, revealing significant suppression of the leading order results.

Contribution

It provides the first complete calculation of NLO electroweak effects on this Higgs production channel at the LHC.

Findings

NLO EW corrections significantly suppress LO contributions.

Electroweak effects are crucial for accurate Higgs production predictions.

Small quark-initiated contributions are also evaluated.

Abstract

The dominant contribution to the Higgs production in association with bottom quark pair at the LHC is gluon-gluon fusion parton subprocess. We present a complete calculation of the next-to-leading order (NLO) electroweak (EW) corrections to this channel. The other small contributions with quarks in the initial state are calculated at tree level. We find that the NLO EW corrections can suppress the leading order (LO) contributions significantly.
