摘要：

We study the lattice QCD ΛcN phase shifts for the3S1-3D1coupled channel using both the leading order covariant chiral effective theory and the next-to-leading order non-relativistic chiral effective field theory(ChEFT).We show that although it is possible to describe simultaneously the3S1and3D1phase shifts and the inelasticity η1,the fitted energy range is quite small,only up to Ec.m.=5 MeV.This raises concerns regarding the consistency between leading/next-to-leading order ChEFT and the lattice QCD simulations.
