Possible $S$-wave $N{D}^{(\ast )}$ and $N{\bar{B}}^{(\ast )}$ bound states in a chiral quark model

Dan Zhang, Dan Yang, Xiao-Fei Wang +1

$S$-wave bound-states composed of a nucleon($N$) and a heavy meson ($D$, $D^{\ast }$, $\bar{B}$ or ${\bar{B}}^{\ast }$) are investigated in both the chiral SU(3) quark model and the extended chi…
