Exploratory study of possible resonances in the heavy meson - heavy baryon coupled-channel interactions
We use a unitary coupled-channel model to study the interactions. In our calculation, SU(3) flavor symmetry is
applied to determine the coupling constants. Several resonant and bound states
with different spin and parity are dynamically generated in the mass range of
the recently observed pentaquarks. The approach is also extended to the hidden
beauty sector to study the interactions. As the
-quark mass is heavier than the -quark mass, there are more resonances
observed for interactions and they are more tightly
bound.Comment: 10 pages, 11 figures, updated to the published versio
