Toponium physics at the Large Hadron Collider
arXiv:2505.03869
Abstract
We examine toponium formation effects in top-antitop pair production at the LHC, focusing on the near-threshold region where non-relativistic corrections are relevant. We discuss their modelling using non-relativistic QCD Green's functions, and show that predictions reproduce features expected from bound-state dynamics, in contrast to pseudo-scalar toy models.
