RE: Probing antimatter in its deepest details at CERN
However, particles and antiparticles have opposite quantum numbers
I remember you once replied in one of my comments in your post that there are some particles that are their own antiparticles; if I'm not mistaking. But in this case, would they have opposite quantum numbers?
Hope I'm not asking a stupid question? :)
Everything you said is correct. And the only number who is its own opposite is 0. Therefore, in order for a particle to be its own antiparticle, it has in particular to be electrically neutral.
This was not a stupid question! :)
Thanks for the quick lectures sir :)
My pleasure :)
