Toponium Production at Future Muon Colliders and in heavy ion ultraperipheral collisions
In the framework of non-relativistic quantum chromodynamics (NRQCD), we systematically investigate the inclusive and exclusive production processes of spin-singlet \(^1S_0\) and spin-triplet \(^3S_1\) toponium at future muon colliders and in Pb--Pb ultraperipheral collisions (Pb--Pb UPC). Using the Coulomb-plus-linear...
