Quarks interact via the strong force, but leptons do not. Both quark and leptons interact via the electromagnetic, weak, and gravitational forces. Elementary particles are classified into fermions and boson. Fermions have half-integral spin and obey the exclusion principle. Bosons have integral spin and do not obey this principle.

Such a theory (which is essentially a grand unified theory plus gravity) has not yet been found, nor is it known whether such a theory even exists.

A few years later ’t Hooft shows that it is a well-posed theory. This predicts the existence of three extremely heavy bosons that mediate the weak force: the Z0 and the W±. These have been found in 1983. There is one more particle predicted by these theories: the Higgs particle. Must be very heavy!
