    Graduate Restriction on terms in the SM lagrangian

    Hello, Just a few questions about a couple of terms in and not in the SM Lagrangian. I'll talk in particular about these fields, and their representations in SU(3) x SU(2) x U(1) Q (3,2,1/6) (left-handed quarks, fermion) U (3,1,2/3) (right-handed up-quarks, fermion) \phi (1,2,-1/2) (higgs...

    Graduate Coupling to gauge fields - charge, doublets, etc.

    Hello, I'm trying to understand the standard model, and I'm confused in a few places. Correct me please, if I seem confused somewhere. I'll give my understanding first, and then a few questions. I'm certain I have a couple of things not straight in my head. Alright, so the standard model has...

    Undergrad Transmitting portion of a transmitter works

    Thanks for the reply, TurtleMeister. I should clarify exactly what I was wondering -- Suppose I already have a signal that I want to transmit, and its already amplified, etc. How do I actually turn that signal into EM waves? I guess, basically, I don't understand how to analyze how an...

    Undergrad Transmitting portion of a transmitter works

    (Update -- please read the third post -- I guess I'm wondering how an antenna works in particular).Hey, I can't seem to find much information on how the actually transmitting portion of a transmitter works -- how does one efficiently generate EM waves? Thanks!(I'm aware that the rough idea is...
