Abstract

The recent (not so recent now) data from the LHC has a reported threshold enhancement in top-antitop production, we want to present a reinterpretation of the the recently published data. We do this in nonlocal quantum field theory and we show that the observed threshold excess can be made to fit by a data-driven nonlocal scale Λ ker Λ ker and small RG effects, while keeping global QCD tests intact. We then contrast the properties of the heavyquark systems highlighting the unique role of the top quark’s decay width in shaping the phenomenology of toponium. We find that toponium becomes a powerful tool for both infrared boundstate dynamics and ultraviolet completion effects opening new avenues for precision tests of QCD.
