摘要:

The quark model encounters a great challengein describing even-parity mesons such as the light scalar mesons below 1 GeV, scalarand axial-vector charmed mesons and the charmonium-like state X(3872).  A common wisdom for the resolution of thesedifficulties lies on the coupled channel effects which will distort the quarkmodel calculations. In this talk we point out that the closeness of strange andnon-strange scalar charmed mesons will lead to the same degeneracy phenomenonin the B meson sector.
