1.10: The W⁺, W⁻, and Z bosons

  • Page ID
  • On the other side a electro-weak interaction is developed by Weinberg and Salam. 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 \(Z^{0}\) and the \(W^{\pm}\). These have been found in 1983. There is one more particle predicted by these theories: the Higgs particle. Must be very heavy!
