英文摘要: Using heavy meson chiral perturbation theory, we have calculated systematically the pion (.rr, K, 11) and heavy pseudoscalar meson S-wave scattering lengths up to O(p3) in the heavy quark symmetry limit. From a lattice simulation, we estimate the unknown low-energy constants and predict all the other unmeasured scattering lengths. We found six channels are attractive, including the isoscalar DK channel. The DK interaction may help to lower the mass of the "bare" charm-strange scalar state in the quark model through the couplechannel effect.
