WebAug 3, 2015 · 7. Consider the Georgi-Glashow model, an gauge theory with a real scalar in the adjoint (thus a 3-vector in the colour space) . The Lagrangian is where everything is as usual regarding the field strength and the covariant derivative. Also, let us write the scalar field in matrix form as where are the Pauli matrices as usual. WebThis culminated around 1968 in a unified theory of electromagnetism and weak interactions by Sheldon Glashow, Steven Weinberg, and Abdus Salam, for which they shared the 1979 Nobel Prize in Physics. [9] [c] Their electroweak theory postulated not only the W bosons necessary to explain beta decay, but also a new

It is noted that the predictions of all the models for \int 1 0 ( F ν p 2 + F ν n 2 ) d ξ are within the range of the present experimental limits.
WebNov 27, 2024 · The Glashow-Salam-Weinberg theory is not asymptotically free. There's a U(1) in the gauge group and also it's Higgsed. I'm not certain anymore, what's the precise statement but if I remember right, one can show that for a wide range of Higgsed local gauge symmetries the resulting models are not asymptotically free, even if there are no …
