We investigate the properties of dibaryons containing $u$ and $d$ quarks in constituent quark model. In constructing ground state wave function, we choose spatial part to be fully symmetric remaining color, isospin, spin antisymmetric so as satisfy Pauli principle. By adapting isospin $\ensuremath{\bigotimes}$ ($IS$) coupling scheme that combines basis function with subsequently this color singlet construct states compatible physical dibaryon. using variational method, then calculate mass...

In this work, we investigate the hadron interactions using three-quark potential in a constituent quark model. Three-quark potentials have only been studied for simple cases because it is difficult to calculate three-color interaction matrix and determine radial dependence of potential. case multiquark system, color can be calculated permutation matrix, but when there are antiquarks, different method must used. order potential, use commutation anticommutation relations SU(3) apply exotic...

The constituent quark model with color-spin hyperfine potential is used to investigate the property of a compact pentaquark configuration $J^p$=$3/2^-$ and isospin=1/2, which most likely quantum number one recently observed exotic baryon states at LHCb.

To compare our results that lattice QCD limit, we search...

We probe effects of the partial chiral symmetry restoration to mass heavy-light mesons in a constituent quark model by changing light quark. Due competing effect between and linearly rising potential, whose contribution energy increases as decreases, meson has minimum value near typically used vacuum. Hence, one decreases consistent with recent QCD sum rule analyses, which show an increasing $D$ order parameter decreases.

Our work identifies origin nuclear body forces including hyperons are called...

We investigate the hadron production from vortical quark-gluon plasma created in heavy-ion collisions. Based on quark-coalescence and statistical hadronization models, we show that total yields summed over spin components are enhanced by local vorticity with quadratic dependence. The enhancement factor amounts to be a few percent may detectable within current experimental sensitivities. also effect is stronger for hadrons larger spin, thus propose new signature of vorticity, which detected...

Based on the fact that constituent quark model reproduces recent lattice result baryon-baryon repulsion at short distance and it includes dynamics with confinement, we analyze to what extent quarkyonic modes appear in phase space of baryons as one increases density before only hence deconfinement occurs. We find baryon density, initial mode appears will involve $d(u)$-quark from a neutron (proton), which leave most attractive ($ud$) diquark intact.

We study the properties of $\mathrm{\ensuremath{\Delta}}$ isobar in symmetric and asymmetric nuclear matter using QCD sum rules approach based on energy dispersion relation.
