Abstract

We examine the effects of soft gluons on Higgs boson production in association with a Z boson at the Large Hadron Collider (LHC). Utilizing the universal cusp anomalous dimensions and splitting kernels, we analyze effects of soft gluons on the gluon fusion ZH process, focusing on the total production cross section as well as the invariant mass distribution at the next-to-leading logarithmic level. Additionally, we estimate the next-to-soft effects on this subprocess to the same level of accuracy. A detailed phenomenological analysis is performed for the 13.6 TeV LHC. Finally, combining these results with those from other subprocesses, we provide comprehensive predictions for the ZH production cross section and the invariant mass distribution that will be valuable for comparison with experimental data from the upcoming LHC run as well as the future hadron colliders.
