I could follow it easily. Almost as if somebody finally explained particle physics experiments in English. 🙂

I have few questions though. Mostly, regarding how I am trying to wrap my imagination around it.

Particle-antiparticle pairs are supposed to annihilate (like that owl, anti-owl did in discord). What stops a quark and an anti quark pair from immediate annihilation. Is the color force between them repulsive to hold them apart?

Is it known that decay time of a known particle can change when they form a composite particle. Say if t1 is decay time for particle x and t2 is of particle y. The decay time of xy is either t3 > t1 or t2 if it gets stable, or t4<t1 or t2 if it becomes more unstable? Is this what you think is happening with toponium, that it is getting more stable as a composite particle? Or you were able to see an even 10^-25s small?
