Referencess on Dynamical Symmetry Breaking

  1. Aug 15, 2005 #1
    I would much appreciate if anyone coud give me some tips/referencess on Dynamical Symmetry Breaking. Namely detailed referrence on Namby Jona-lasinio model of mass for particles.

    If you mean "Namby" as in Yoichiro Nambu, then the symmetry breaking paper that you want is

    Y. Nambu and G Jona-Lasinio, Phys. Rev. v.122, p.345 (1961).

    However, you need to also look at Anderson's work on the Goldstone boson that showed that such a thing can have a mass

    P W Anderson, Phys. Rev. v.130, p.439 (1963).

    Both of these are crucial in the Higgs paper:

    P W Higgs, Phys. Lett. v.12, p.132 (1964).

    Thank you for referrences much appreciate ur help.
    Unfortunateli im not quite familiar with math of QFT
    could anybody help me...in following..

    In Paper Y. Nambu and G Jona-Lasinio, Phys. Rev. v.122, p.345 (1961). in section III Authors are getting formula (3.4) to define self-energy part of particle. How does that formula come out? That self-energy part it's a actuaaly mass operator?

    Thks a lot

    I can't comment about this particular part since I didn't study the paper that closely. However, the self-energy term usually comes out of the single-particle Green's function, often called the propagator in QFT. It's form depends totally on the kind of interactions you are considering, i.e. how many higher order coupling.

    The only references I would recommend on this is Mattuck's "Feynman Diagram in Many-Body Problem" and Mahan's "Many-Particle Physics".
