Abstract The ladder kernel of the Bethe–Salpeter equation is amended by introducing a different flavor dependence of the dressing functions in the heavy-quark sector. Compared with earlier work this allows for the simultaneous calculation of the ma

We present results for the $\eta_c$-nucleus bound state energies for various nuclei using an effective Lagrangians approach. The attractive potentials for the $\eta_c$ in the nuclear medium originate from the medium-modified intermediate $D D^{*}$ st

Inspired by the recent development of an algebraic model which provides an adequate and unified description of the internal structure of the lowest-lying pseudo-scalar mesons, belonging both to the light quarks sector and to the one of heavy quarks,

By extending the previous works that two of the present authors were involved, we estimate for the first time the $$\varUpsilon $$ and $$\eta _b$$ as well as $$B^*$$ meson mass shifts (scalar potentials) in symmetric nuclear matter. The main interest

Physical Review
In-medium valence-quark distributions of $\pi^+$ and $K^+$ mesons in symmetric nuclear matter are studied by combining the Nambu--Jona-Lasinio model and the quark-meson coupling model. The in-medium properties of the current quarks, which are used as

We study dynamical chiral symmetry breaking for quarks in the fundamental representation of $SU(N_c)$ for $N_f$ number of light quark flavors. We also investigate the phase diagram of quantum chromodynamics at finite temperature $T$ and/or in the pre
