Thank you! Ok, I understand what happens, when I turn on the vev, but not exactly why. When I have a SM Lagrangian I know what happens. I introduce a Higgs potential, decompose it and see immediately the mass dependence. But now, I have this operator coupling HHO and I don't know how to...

Ok, what I'm looking for is, why I introduce a mass scale when I turn on a vev. Isn't that the same? I thought, when I introduce a mass scale, the coupling gets energy dependent and it flows away from the fixed point... Hmmm... I think tomorrow I will look for a textbook... Thanks a lot!

Hi! That's my first thread and I apologize for my bad English, but there's a question in my mind that makes me crazy... At the moment I'm working on Unparticle Physics especially on the coupling between the SM Higgs sector and the unparticle sector. There is a paper by Fox, Rajaraman...
