We describe the mixing of qq¯ pseudoscalar states with longitudinal qq¯ axial-vector states, making use of a relativistic quark model that includes a model of confinement. (In the absence of the confinement model, our model reduces to the Nambu–J

We study the nonstrange scalar-isoscalar states of a generalized Nambu{endash}Jona-Lasinio model that includes the {close_quote}t Hooft interaction and a model of confinement. We also include coupling of the q{bar q} states to the two-pion continuum

A recent analysis by T{umlt o}rnqvist and Roos suggests that the {sigma} meson has a mass of 860 MeV with a width of 880 MeV. In this work we calculate the properties of the {sigma} meson using a generalized Nambu{endash}Jona-Lasinio model that inclu

We present a relativistic model of the nucleon based upon a quark-diquark structure that emerges from a study of the Nambu-Jona-Lasinio model. Similar calculations, made by other authors, have been carried out after a Wick rotation is performed. Thes

We describe an extended version of the Nambu\char21{}Jona-Lasinio (NJL) model that includes a description of confinement. It is necessary to incorporate some description of confinement in order to discuss the properties of the sigma, rho, and omega m

We discuss the calculation of QCD sum rules for hadrons in matter from the point of view of nuclear many-body theory and treat the sum rule for the rho meson as an example. We describe the factorization approximation that is used to calculate four-qu
