Title: On the higher-loop effective action in NJL model
Abstract:The 3-loop effective action and effective potential in Nambu - Jona-Lasinio model are calculated. The problem of vanishing contributions in the higher orders is discussed. The general form of such con...The 3-loop effective action and effective potential in Nambu - Jona-Lasinio model are calculated.
