Physics Asked by wilada on February 12, 2021
I’m beginning to study some particle physics and as I understand, all particles have an antiparticle that is identical besides charge, which is inverted. Thus I understand that there is a difference between an anti-electron and a proton (or vice versa) but since (as far as I can tell) the up and down particles have the same mass, is the anti-up quark a down quark?
No. The anti-up has charge -2/3 and the down has charge -1/3. They do have different masses also.

The antiup quark has more charge than down quark. Also they can combine to form pion that has a negative charge.
