Very great thanks again. This is for a seminar and we have been asked a very tough question. Renormalisation is apparently a vast area with sections of it being also vast research areas in their own right!
Each of us has to propose some change to the Lagrangian of the Standard Model, which...
Thanks very much for your answers.
So I take it that if I propose a Higgs field which is only different from the usual Higgs by having a different self-interaction with no terms in Φ of a higher power than 4, and it functions in exactly in the same way as the Higgs does in the usual Standard...
It would also be good to know the following: if you proposed a Higgs Lagrangian which is only different in that it has a different self-interaction to the usual one, but which is still symmetric under gauge transformations, and which breaks in the usual way as φ → v + H(x), will the EW theory...
Thanks very much for your help. Happy for you to choose the reference. It would be handy if it were online. Below is the question which I am trying to answer:-
I have proposed a variant of the Standard model where the usual Higgs field (Lagrangian) expression breaks to a different expression...
Hi Everyone! Hope everyone is really enjoying pushing the Physics frontiers!
Really need some help here. In the Electroweak sector of the Standard Model, it is apparently the case that the success of renormalisation to remove the Ultraviolet Divergence relies on the fact that at high energies...
