Description
We provide an update on QCD predictions for top-quark pair production close to threshold including bound state effects at the Large Hadron Collider (LHC) [arXiv:2412.16685]. We compute the top-quark pair invariant mass distribution, including Coulomb resummation for bound-state effects, as well as threshold resummation for emissions of soft and collinear gluons. We discuss uncertainty estimates and present a proposal for the use of these predictions in experimental analyses. We comment on the impact of these effects in top-quark mass extraction using state-of-the-art top-quark data at the LHC.
