Abstract
We present precise theoretical results for the $ZH$ production cross section and invariant mass distribution at the Large Hadron Collider (LHC) taking into account the effects of soft gluons. We improve both quark-initiated and gluon-initiated subprocesses through threshold resummation within the QCD framework and present combined results relevant for $13.6$ TeV LHC.
List of changes
"1. Provide some discussion of the contribution of the soft-gluon logarithms at fixed order (either percentage or actual numbers)."
We have added the following sentence highlighting the contributions from SV logarithms on page-2, in the introduction:
Indeed, the threshold soft-virtual (SV) logarithms at NLO can contribute to 90 − 99% of the complete NLO results in the range Q = 350 − 2000 GeV.
"2. Delete or modify the sentence about ‘essential to resum ... to all orders’. "
We have rephrased the sentence accordingly on page-2, second paragraph: By resumming these soft-virtual (SV) logarithms to all orders, one obtains predictions that are stable and well-behaved across the relevant kinematic regions.
"3. State that the results are prescription dependent. "
We have added a sentence on this on page-3, after eq.(3): Other prescriptions, for instance the Borel prescription, may lead to differences with respect to the minimal prescription that are confined to subleading terms.
