| 摘 要： | We study the lattice QCD ΛcN phase shifts for the 3S1-3D1 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 3S1 and 3D1 phase shifts and the inelasticity η1,the fitted energy range is quite small,only up to E<...
