Properties of $\Lambda,~\Xi^0$ hypernuclei and neutron stars are investigated in quark mean field model with pion and gluon corrections. Firstly, $u, ~d$, and $s$ quarks are confined by relativistic harmonic oscillator potentials to generate the baryons, like nucleon, $\Lambda, ~\Sigma$, and $\Xi$ hyperons. The effects of pion-quark coupling and one-gluon exchange are considered perturbatively. Then, the baryons interact with each other through exchanging $\sigma, ~\omega,$ and $\rho$ mesons… Expand

The quark mean-field (QMF) model is applied to study the single $\Lambda^+_c$ hypernuclei. The charm baryon, $\Lambda^+_c$, is constructed by three constituent quarks, $u, ~d$, and $c$, confined by… Expand

The possibility of the appearance of $\mathrm{\ensuremath{\Delta}}$(1232) isobars in neutron star matter and the so-called $\mathrm{\ensuremath{\Delta}}$ puzzle is investigated in a relativistic… Expand

We propose the new quark mean-field bag (QMFB) model by incorporating the bag confinement mechanism in the original quark mean-field model. Nuclear matter and neutron star properties are studied with… Expand

We systematically study the properties of single-Λ,Ξ, and Σ hypernuclei within the framework of relativistic mean-field model. The YN coupling constants are constrained according to the experimental… Expand
