The Pseudoscalar Meson and Charmed Baryon Scattering Lengths [PDF]
Zhan-Wei Liu, Shi-Lin ZhuWe have calculated the scattering lengths between the pseudoscalar meson and charmed triplet, sextet, and excited sextet baryon to the third order with the heavy baryon chiral perturbation theory. The chiral expansion of the pion channels converges well.View original: http://arxiv.org/abs/1205.0467
