Abstract
- With a quark level interaction, we give a unified description of the loosely bound molecular systems composed of the heavy flavor hadrons (D ¯ , D ¯ ∗) , (Λ c , Σ c , Σ c ∗) , and (Ξ c , Ξ c ′ , Ξ c ∗) . Using the P c states as inputs to fix the interaction strength of light quark-quark pairs, we reproduce the observed P cs and T cc + states and predict another narrow T cc ′ + state with quantum numbers [ D ∗ D ∗ ] J = 1 I = 0 . If we require a satisfactory description of the T cc + and P c states simultaneously, our framework prefers the assignments of the P c (4440) and P c (4457) as the [ Σ c D ¯ ∗ ] J = 1 / 2 I = 1 / 2 and [ Σ c D ¯ ∗ ] J = 3 / 2 I = 1 / 2 states, respectively. We propose the isospin criterion to explain naturally why the experimentally observed T cc , P c , and P cs molecular candidates prefer the lowest isospin numbers. We also predict the loosely bound states for the bottom di-hadrons. [ABSTRACT FROM AUTHOR]
