Toponium: Implementation of a toponium model in FeynRules
Jing-Hang Fu, Yu-Jie Zhang, Guang-Zhi Xu +1
Toponium -- a bound state of the top-antitop pair () -- emerges as the smallest and simplest hadronic system in QCD, with an ultrashort lifetime ($τ_t \sim 2.5\times 10^{…

Toponium: the smallest bound state and simplest hadron in quantum mechanics
Jing-Hang Fu, Yu-Ji Li, Hui-Min Yang +3
We explore toponium, the smallest known quantum bound state of a top quark and its antiparticle, bound by the strong force. With a Bohr radius of ~m and a lifetim…
