Ah @fzero so you mean ##\delta S/\delta F^{\lambda \tau}= \frac{\delta S}{g^{\lambda \lambda'}g^{\tau \tau'}\delta F_{\lambda'\tau'}}##?

@fzero I have a question, when @beyondthemaths wrote at the very beginning ##1/2N_{IJ}F^I_{\mu\nu}\tilde{F}{J\mu\nu}## and then the functional derivative as you have defined it will be something like ##\frac{\delta S}{\delta F_{\lambda \tau}^K}##, what I notice was that ##F_{\lambda \tau}^K##...

I am talking fullbright to MS rather than that to PhD

I mean if it so unusual to do stuff separately?

What do you mean by worst option? Isn't a Masters degree followed then by PhD degree?

Hello! From your own experience and because of your familiarity with your local institutes, what are the best universities in which one can pursue masters degree for 2016-2018 as a two year program and if also you are knowledgeable about universities that offer a one year MSc program as in UK...

The question was: Why is it if the couplings of the neutral intermediate boson to neutrinos are flavor preserving then ... They did not say any thing about the "same strength" you mentioned in what I quoted. Did you assume that to make the sentence hold?

But the problem doesn't talk about equal couplings?

SO yes that is what I meant, that you can produce a Higgs in that way. If so, then the CM is how @Einj posted, no? @Einj, how would I find invariants in this case?

But you were already talking about strength rather than flavors. I am confused now.. What happened? Is it that conserved flavors make the matrix proportional to identity matrix or is it not? :(

If an electron-positron is decaying into Higgs and then from Higgs into fermions. What is CM frame in this case? Let us say that electron has momentum $$p_{e^-}=p_1$$ The positron has a momentum $$p_{e^+}=p_2$$ The fermion has momentum $$ p_{f} = q_1$$ and the other one has momentum...

Please elaborate, was that a question or an answer? If an answer, why would the interaction Hamiltonian commute with the mass matrix if the flavor is conserved. I can't relate.

Thank you @Orodruin

So electroweak theory says if flavors are of the same strength then the representative matrix is identity? If so, why does it say so?

Then why is that when flavors are of the same strength then the matrix should be proportional to identity?
