A flux-tube model of hadrons is used to study the modification of hadronic properties in nuclear matter. It is shown that nuclear binding and the EMC effect are consequences of partial deconfinement, and that complete deconfinement occurs at about six times normal nuclear density. It is predicted that nucleon resonances are much more strongly bound than the nucleon, and that there is a maximum l beyond which nucleon resonances do not exist in nuclear matter.

The two-phase system consisting of nucleons and six-quark clusters is investigated. The interaction between nucleons and six-quarks is represented by a sum of the Fermi and Yukawa potentials. The temperature behavior of nucleon and six-quark concentrations versus density is found. It is shown that with a normal nuclear density, six-quark clusters may amount to about 10%, which is in agreement with experiment.

Deconfinement Phase Transition

We derive the equation of state (EOS) of nuclear matter within a generalised Nambu–Jona–Lasinio (NJL) model which saturates at normal nuclear density, ρ0. Chiral symmetry is restored at ~ 6–7 ρ0. At low densities the model includes clustering and reproduces the properties of nuclear matter namely binding energy and incompressibility. At high densities (ρ>3–4.5 ρ0) quark matter is more stable than nuclear matter. The confinement-deconfinement phase transition is studied.

We have investigated the Regge trajectories of exotic hadrons by considering different possible pentaquark configurations with finite quark mass in the flux tube model. Significant deviation is observed in the linear behavior of the Regge trajectories for pentaquark systems in view of the universal value of the Regge slope parameter for hadrons. The modified Regge trajectories are also compared with the available experimental and lattice data. It is observed that the nonlinear Regge trajectories of such pentaquark systems can be well described by the relativistic corrections in view of the current quark masses and the high rotational speed of the quarks at the end of flux tube structure.

Good Agreement

In the framework of the quasiparticle approach, the ground state mass of heavy pentaquarks have been investigated in diquark–diquark–antiquark picture and the higher states are investigated in the mass loaded flux tube model where two light diquarks are supposed to be linked by a flux tube to the heavy quark. The Regge trajectories for heavy pentaquarks have been studied. The Regge slope (α) of these particles have been obtained as ≈1 GeV2 which indicates that the Regge trajectory follows the linearity conditions with universal value of α (~ 1 GeV2). The ground state mass of doubly charm and doubly bottom baryons like [Formula: see text] have also been investigated in quasiparticle approach. The results are found to be in reasonably good agreement with the experimental and other theoretical estimates.
