Main Question or Discussion Point

Could anyone explain me some things related to Nambu-Jona-Lasinio model
or at least give me a reference to some papers about it. I'm trying to understand
some basis of this model but I cannot find good literature.

What is the intuitive reason why this model predicts a condensation of quarks
and when this condensate is created (at what energies)?

Why it is said that this model spontaneously breaks the chiral and axial symmetry?

What does dynamical mass generation means in relation to this model?

Thanks for help.

Maybe a good starting point is the talk of Nambu on nobel.org.

Nambu nobel price lecture
"nobelprize.org/nobel_prizes/physics/laureates/.../nambu_lecture.pdf"[/URL]
is indeed a good starting point. More detaild information might be found in
original paper by Nambo and Jona-Lasinio (which is unfortunatelly a bit too technical for me):
[PLAIN]http://prola.aps.org/pdf/PR/v122/i1/p345_1" [Broken]
I'm stuck on the fourth page. Can anyone explain me the idea of derivation of formula (3.4).

Cf. Freundlich and Lurie, Nucl. Phys. B18 (1970) 141-150.
