Abstract: We study the heavy quark spin (HQS) multiplet structure of P-wave $Q\bar{Q}qqq$-type pentaquarks treated as molecules of a heavy meson and a heavy baryon. We define the light-cloud spin (LCS) basis decomposing the meson–baryon spin… read more here.

DOI: 10.1103/physrevd.105.034004
Abstract: We study the correlation between the quark spin and orbital angular momentum inside the pion meson. Similar to the case inside the nucleon, the longitudinal spin-orbit correlation in pion can be expressed in terms of… read more here.

Abstract: We study the structure of heavy quark spin (HQS) multiplets for heavy meson-baryon molecular states in a coupled system of $\bar{P}^{(*)}\Sigma_{Q}^{(*)}$, with constructing the one-pion exchange potential with S-wave orbital angular momentum. Using the light… read more here.

DOI: 10.1103/physrevlett.122.242001
Abstract: A recent analysis by the LHCb Collaboration suggests the existence of three narrow pentaquarklike states-the P_{c}(4312), P_{c}(4440), and P_{c}(4457)-instead of just one in the previous analysis [the P_{c}(4450)]. The closeness of the P_{c}(4312) to the… read more here.

DOI: 10.1140/epjc/s10052-019-6929-7
Abstract: We study the implications for and and decays that can be deduced from heavy quark spin symmetry (HQSS). Identifying the odd parity and resonances as HQSS partners, with total angular momentum–parity for the light degrees… read more here.
