I have found these online: Toponium: the smallest bound state and simplest hadron in quantum mechanics (Feb 2025)

For sure if we get a stronger signal we can understand more of the threshold effects. About the discovery thing, yes, maybe we could call it an "observation". It is largely a question of...

Maybe toponium could be used to measure better the top mass? I would not call toponium a discovery, it's just an expected bound state.

Thank you very much for blogging this! This is of profound interest to me because I have a strong interest in theories where the Higgs is some kind of toponium (e.g. this may be the case in some...

Add another. Though have to admit, a PhD stats class makes me shudder ;)
