Spectrum of the doubly charmed molecular pentaquarks in chiral effective field theory
arXiv:2102.05868 · doi:10.1103/PhysRevD.103.116017
Abstract
We perform a systematic study on the interactions of the systems within the framework of chiral effective field theory. We introduce the contact term, one-pion-exchange and two-pion-exchange contributions to describe the short-, long-, and intermediate-range interactions. The low energy constants of the systems are estimated from the scattering data by introducing a quark level Lagrangian. With three solutions of LECs, all the systems with isospin can form bound states, in which different inputs of LECs may lead to distinguishable mass spectra. In addition, we also investigate the interactions of the charmed-bottom , , and systems. Among the obtained bound states, the bindings become deeper when the reduced masses of the corresponding systems are heavier.
