$P_c$ pentaquarks with chiral tensor and quark dynamics

Yasuhiro Yamaguchi, Hugo Garcia-Tecocoatzi, Alessandro Giachino +4

We investigate the hidden-charm pentaquarks as superpositions of ${\Lambda }_c{\bar{D}}^{(\ast )}$ and ${\Sigma }_c^{(\ast )}{\bar{D}}^{(\ast )}$ (isospin $I=1/2$) meson-baryon channels coupled to a $uudc\bar{…
