Spontaneous generation of the Nambu –Jona-Lazinio interaction in quantum chromodynamics with two light quarks


In QCD with two light quarks with application of Bogolubov quasi-averages approach a possibility of spontaneous generation of an effective interaction, leading to the Nambu – Jona-Lazinio model, is studied. Compensation equations for form-factor of the interaction is shown to have the non-trivial solution leading to theory with two parameters: average low… (More)
