The particles, termed Zb, contain both one bottom quark and one anti-bottom quark.
Eh? Why don't they go poof?

I expect they do. I don't know, but I suspect the particle has an extremely short lifetime.

So they have managed to make matter that also incorporates its antimatter? That's a neat trick.

Well, positronium's been around for quite a while.

Oh, didn't know. Sounds impossible, but those crazy scientist dudes can do amazing shit.
