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!
