Improved understanding of soft gluon effects at threshold.

Refined invariant mass distribution calculations.

Abstract

We present precise results for the $ZH$ production cross-section and invariant mass distribution at the LHC, taking into account the effects of the leading and sub-leading soft gluons. We improve both quark-initiated and gluon-initiated subprocesses through threshold resummation within the QCD framework.
