Abstract: (APS)

We study the DN and D*N interactions to probe the inner structure of Σc(2800) and Λc(2940) with the chiral effective field theory to the next-to-leading order. We consider the contact term, one-pion-exchange and two-pion-exchange contributions to characterize the short-, long-, and mid-range interactions of the D(*)N systems. The low energy constants of the D(*)N systems are related to those of the NN¯ interaction with a quark level Lagrangian that was inspired by the resonance saturation model. The Δ(1232) degree of freedom is also included in the loop diagrams. The attractive potential in the [DN]J=1/2I=1 channel is too weak to form a bound state, which indicates that the explanation of Σc(2800) as the compact charmed baryon is more reasonable. Meanwhile, the potentials of the isoscalar channels are deep enough to yield the molecular states. We obtain the masses of the [DN]J=1/2I=0, [D*N]J=1/2I=0, and [D*N]J=3/2I=0 systems to be 2792.0, 2943.6, and 2938.4 MeV, respectively. The Λc(2940) is probably the isoscalar D*N molecule considering its low mass puzzle. Besides, the Λc(2940) signal might contain the spin-12 and spin-32 two structures, which can qualitatively explain the significant decay ratio to D0p and Σcπ. We also study the B¯(*)N systems and predict the possible molecular states in the isoscalar channels. We hope experimentalists could hunt for the open charmed molecular pentaquarks in the Λc+π+π- final state.
