Quark-Hadron Phase-Transition in an Extended NJL Model with Scalar-Vector Interaction
T. -G. Lee, Y. Tsue, J. da Providencia +2
The quark-hadron phase transition at finite temperature and baryon chemical potential is investigated in an extended NJL model with scalar-vector eight-point interaction by compari…
Scalar and Pseudoscalar Glueball Masses within a Gaussian Wavefunctional Approximation
Y. Tsue
The lowest scalar and pseudoscalar glueball masses are evaluated by means of the time-dependent variational approach to the Yang-Mills gauge theory without fermions in the Hamilton…
Color-Singlet Three-Quark States in the su(4)-Algebraic Many-Quark Model
Y. Tsue, C. Providencia, J. da Providencia +1
As announced in last paper by the present authors, the color-singlet three-quark states are investigated for the case of the spherical j-j coupling and L-S coupling shell models. T…
Re-formation of Many-Quark Model with the su(4)-Algebraic Structure in the Schwinger Boson Realization
Y. Tsue, C. Providencia, J. da Providencia +1
The energy eigenstates for the su(4)-algebraic model for many-quark system obtained by the present authors in the Schwinger boson space are reconsidered in the original fermion spa…
