Abstract

We study the lattice QCD Λ_c N phase shifts for the ³ S ₁-³ D ₁ coupled 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 the ³ S ₁ and ³ D ₁ phase shifts and the inelasticity η ₁, the fitted energy range is quite small, only up to E _c.m. = 5 MeV. This raises concerns regarding the consistency between leading/next-to-leading order ChEFT and the lattice QCD simulations.
