“…Bailin et al [24] have studied the SQM considering diquark correlation as an intermediate stage of nuclear matter and described the correlation as high density QCD perturbation in NJL model. Diquark correlation has been studied by Bhattacharya et al [15] considering the effect of choromoelectromagnetic nature of QCD vacuum in the context of composite fermion model. Stotami et al [25] have pointed out that quark matter with strong magnetic field indicate the possibility of compact star whereas Noronha et al [26] indicated the possibility of forming diquark Cooper pair participation in dense quark matter.…”

“…Contributions for different diquark correlations to thermodynamic potential energies have been estimated with quasi particle model of diquark suggested by us. [ 15 ] The variation of thermodynamic potential with chemical potential has been computed and are displayed in Figure 1. It shows the variation of thermodynamic potential with chemical potential for different diquarks.…”

“…Recently we have suggested a composite fermion model for diquark. [ 15 ] It is known that in the presence of the magnetic field quantum particles behave like a quasi particle (composite fermions [CF]) incorporating the effect of the magnetic field. [ 16 ] The effective mass of the composite fermion is described as self energy and it depends on the gauge choice of Hamiltonian.…”

Properties of strange quark matter (SQM) have been studied as diquark matter with diquark correlation. The dense SQM is under strong magnetic field due to electroweak interaction of quarks. Here it is suggested that u, d, s quarks get correlated to form diquark matter of different flavors. The diquarks are suggested to behave like quasiparticles under the influence of strong magnetic field inside the dense quark matter. In the current work diquarks are described as the composite fermions which behave like quasiparticle under the strong magneticfield in an analogy with the electrons behaving in strong magnetic field. The thermodynamic potential for SQM has been estimated and behavior is studied with respect to chemical potential. The equation of state and the velocity of sound through SQM are also studied. Some interesting observations are made. It is suggested that the composite fermion picture of diquark correlation lowers the binding energy of the system making the SQM a more stable state.

“…Linear Regge trajectories are also observed in [10], [11], [12], [13] while non-linear Regge trajectories are observed in ref. [8,14]. Regge trajectories for charmonium and bottomonium mesons with spinless Salpeter-type equation by employing the Bohr-Sommerfeld quantization approach are presented by Chen in ref.…”

In this paper, masses and radii of Σ − u states hybrid charmonium mesons are calculated by numerically solving the Schrödinger equation with non-relativistic potential model. Results for calculated masses of Σ − u states charmonium hybrid mesons are found to be close to the results obtained through lattice simulations. Calculated masses are used to construct Regge trajectories. It is found that the trajectories are almost linear and parallel.
