Query: Pseudoscalar Goldstone Bosons Scattering off Charmed Baryons with Chiral
  Perturbation Theory   We have systematically calculated the pseudoscalar Goldstone boson and
charmed baryon scattering lengths to the third order with heavy baryon chiral
perturbation theory. The scattering lengths can reveal the interaction of $K
\Lambda_c$, $K \Sigma_c$, $\pi \Omega_c$ etc. For each channel, we take into
account of the interaction between the external particle and every possible
charmed baryon in the triplet, sextet, and excited sextet. We use dimensional
regularization and modified minimal subtraction to get rid of the divergences
in the loop-diagram corrections. We notice that the convergence of chiral
expansion for most of the channels becomes better after we let the low energy
constants absorb the analytic contributions of the loop-diagram corrections and
keep the nonanalytic terms only.
