Microscopic study of neutron-rich Dysprosium isotopes
Carlos E. Vargas, Victor Velazquez, Sergio Lerma
Microscopic studies in heavy nuclei are very scarce due to large valence spaces involved. This computational problem can be avoided by means of the use of symmetry based models. Gr…
Exact Solution of the Isovector Proton Neutron Pairing Hamiltonian
J. Dukelsky, V. G. Gueorguiev, P. Van Isacker +3
The complete exact solution of the T=1 neutron-proton pairing Hamiltonian is presented in the context of the SO(5) Richardson-Gaudin model with non-degenerate single-particle level…
A schematic model for QCD. III : Hadronic states
M. Nunez, S. Lerma, P. O. Hess +3
The hadronic spectrum obtained in the framework of a QCD-inspired schematic model, is presented. The model is the extension of a previous version, whose basic degrees of freedom ar…
Modelling Pentaquark and Heptaquark States
M. Nunez, S. Lerma, P. O. Hess +3
A schematic model for hadronic states, based on constituent quarks and antiquarks and gluon pairs, is discussed. The phenomenological interaction between quarks and gluons is QCD m…
A schematic model for QCD II: finite temperature regime
S. Jesgarz, S. Lerma, P. O. Hess +2
A schematic model for QCD, developed in a previous paper, is applied to calculate meson properties in the high temperature (up to 0.5 GeV) regime. It is a Lipkin model for quark-an…
A schematic model for QCD at finite temperature
S. Lerma, S. Jesgarz, P. O. Hess +2
The simplest version of a class of toy models for QCD is presented. It is a Lipkin-type model, for the quark-antiquark sector, and, for the gluon sector, gluon pairs with spin zero…
