Hidden-Charm and Bottom Meson-Baryon Molecules Coupled with Five-Quark States
2018
We investigate the hidden-charm and hidden-bottom pentaquarks as meson-baryon molecules coupled to the five-quark states. As a result of our calculation it emerges that in the charm sector, one needs to add the five-quark potential to the pion exchange potential in order to produce bound and resonant states, whereas, in the bottom sector, the pion exchange interaction alone is strong enough to produce states. Thus, from this investigation, it comes out that the hidden-bottom pentaquarks are more likely to be produced than their hidden-charm counterparts, and, for this reason, we suggest that the experimentalists should look for the hidden-bottom pentaquarks.
