Scientific paper

Within the framework of the heavy quark effective theory, QCD sum rules are
used to calculate the masses of p-wave (c-bar s) states. The results for 0^+
and 1^+ states with the angular momentum of the light component j_l=1/2 are
consistent with the experimental values for D_s(2317) and D_s(2457),
respectively.
