| dc.abstract.en | The LHCb people saw this pentaquark thing, and it’s made people rethink how hadrons work, since it doesn’t fit the usual three-quark idea. Before, most theories said it was just one hadronic molecule, mostly made of $\Sigma_{c}\overline{D}^{*}$. But that’s too simple, because it misses how it interacts with other things nearby and doesn’t consider short-range stuff. So, we thought about the pentaquark P$_{c}$(4550)$^{+}$ as like, a linked-up molecular state because of spin-orbit stuff. We looked into the pentaquark P$_{c}$(4550)$^{+}$ using a linked-channel thingy, with spin-orbit stuff included. We made a model with two linked hadronic channels, $\Sigma_{c}^{+}\overline{D}^{0}$ and $\Sigma_{c}^{+}\overline{D}^{*0}$ they interact with Yukawa-type potentials. We solved some Schrödinger equations and checked out binding energies, spatial densities, and radial wave functions. What we found says that P$_{c}$(4550)$^{+}$ is probably a quasi-bound molecular state near the $\overline{D}^{*}\Sigma_{c}$ threshold. | |
