Hypermatter in chiral field theory

A generalized Lagrangian for the description of hadronic matter based on the linear -model is proposed. Besides the baryon octet, the spin-0 and spin-1 nonets, a gluon condensate associated with broken scale invariance is incorporated. The observed values for the vacuum masses of the baryons and mesons are reproduced. In the mean-field approximation, vector and scalar interactions yield a saturating nuclear equation of state. Finite nuclei can also be reasonably described. The condensates and the effective baryon masses at finite baryon density and temperature are discussed.
