摘要：

The K-meson spectroscopy is studied in the static limit of the s-quark, which is motivated by the heavy quark symmetry. The spin-parity of the light degrees of freedom s(l)P is a good quantum number to classify the K mesons as well as the D and B mesons. Then, K1(1270) is assigned to be the s(l)P=(3/2)+ state and K1(1400) to be the s(l)P=(112)+ state. Our result will be tested in the mass differences between the spin one and two states of D and K mesons. The precise experimental decay widths of these mesons will also reveal the availability of the static limit of the s-quark system.
