Hidden Charm Pentaquark $P_c(4380)$ and Doubly Charmed Baryon ${\Xi }_{cc}^{\ast }(4380)$ as Hadronic Molecule States

Yuki Shimizu, Masayasu Harada

We study hadronic molecular states in a coupled system of $J/\psi N-{\Lambda }_c{\bar{D}}^{(\ast )}-{\Sigma }_c^{(\ast )}{\bar{D}}^{(\ast )}$ in $I(J^P)=\frac{1}{2}({\frac{3}{2}}^{-})$ channel, using the complex sca…
