On Recent measurements of Toponium Threshold Enhancement in Entire-Function-Regulated Nonlocal Quantum Field Theory

We investigate the recently reported threshold enhancement in top-antitop production at the LHC in a finite, gauge-covariant, entire-function-regulated nonlocal quantum field theory framework. Our results demonstrate that the observed threshold excess can be consistently accommodated by a data-driven ${\mathrm{\Lambda }}_{\mathrm{k}\mathrm{e}\mathrm{r}}$ and small RG effects, while keeping global QCD tests intact. We quantify and contrast the key properties of the three heavyquark systems such as charmonium and bottomonium, highlighting the unique role of the top quark’s decay width in shaping the phenomenology of toponium. Toponium emerges as a powerful laboratory for both infrared boundstate dynamics and ultraviolet completion effects opening new avenues for precision tests of QCD.
