WebChiral theories with spontaneous symmetry breaking such as the Nambu-Jona-Lasinio (NJL) model lead to the existence of a scalar mode. We present in a detailed manner how the corresponding low momentum effective lagrangian involving the scalar field can be constructed starting from the NJL model. WebThe CJT formalism can be viewed as a prescription for computing the eﬀective action of a given theory. In general, the CJT formalism resums one-particle irreducible diagrams to all orders. The stationarity conditions for the eﬀective action are nothing but Schwinger–Dyson equations for the black waitress apron

WebAbstract. The finite temperature effective potential for a scalar field with Φ 6 interaction is calculated by extending the CJT formalism for composite operators. It is found that unrenormalized terms appear in the effective potential due to the presence of an unrenormalized mass term. Nonzero turning points are obtained both for positive and ...
