Are Quarks the smallest elementary particles possible?
In: Physics
Well, it’s not clear that the electron (or frankly any of these particles) has “width”, so that would be the smallest. Physics typically uses mass instead of shape for precisely that reason. In the mass sense electrons and neutrinos have less mass than a quark. The photon and gluon have no mass, so that’s the limit there.
We don’t have any experiments that break quarks into smaller things.
