I would much appreciate if anyone could give me some tips/referencess on Dynamical Symmetry Breaking. Namely detailed referrence on Namby Jona-lasinio model of mass for particles.

Unfortunateli I am 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
Dynamical symmetry breaking is a phenomenon that occurs in physical systems where a symmetry present in the underlying equations is spontaneously broken at the observed level. This results in the system exhibiting different behavior than what would be expected based on the symmetry of the equations.
Dynamical symmetry breaking can occur through a variety of mechanisms, such as the Higgs mechanism in particle physics or the chiral symmetry breaking in quantum chromodynamics. In general, it is caused by the interactions between different components of a system, which lead to the spontaneous breaking of symmetries.
One of the most well-known examples of dynamical symmetry breaking is the Higgs mechanism in particle physics, which explains how particles acquire mass through interactions with the Higgs field. Another example is the breaking of chiral symmetry in quantum chromodynamics, which explains the properties of quarks and gluons.
Dynamical symmetry breaking has important implications in many areas of physics, including particle physics, condensed matter physics, and cosmology. It allows for a deeper understanding of the fundamental building blocks of the universe and can help explain the behavior of complex systems.
Yes, dynamical symmetry breaking has been observed in many experiments, such as the discovery of the Higgs boson at the Large Hadron Collider. It can also be observed in condensed matter systems, such as the breaking of rotational symmetry in liquid crystals. However, it can be challenging to directly observe and study dynamical symmetry breaking due to its inherently nonlinear and complex nature.
