| contents | Towards New States of Matter Fábio L. Braghin Física, Astronomía y Matemáticas A linear realization of flavor SU(3) × SU(3) symmetry is developped with scalar and pseudoscalar mesonscoupled to baryons and massive vector fields. This system may be also coupled to colored quarks and gluons,which are expected to be deconfined above a critical range of energy densities and seemingly inside baryons.The coupling to vector fields may lead to finite density baryonic and also anti-baryonic matter. Prescriptions forthe stability equation which yields bound systems is verified. A qualitative discussion of the possible resulting(QCD - type) phase diagram is discussed including the possibility of finding several kinds of superfluid (andeventually superconductive) states. Some bosonic fields are assumed to have non zero expected values, at leastat low energies, corresponding to dynamical symmetry breakings. A generalized symmetry radius is found andthe masses of the particles are found to vary with density. Possible relevance to relativistic heavy ion collisionis pointed out. 2004 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46434514 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.3A Vol.34 |
