Abstract
We summarise updated QCD predictions for top-quark pair production near threshold including bound-state effects at the LHC. We compute the invariant-mass distribution for toponium production, combining Coulomb-like interaction with soft-gluon threshold resummation. We quantify the size of the enhancement with respect to fixed-order QCD, discuss uncertainty estimates and present a proposal for the use of these predictions in experimental analyses.
