Ds(2317) and Ds(2457) from HQET Sum Rules

摘要: Within the framework of the heavy quark effective theory, QCD sum rules are used to calculate the masses of p-wave ¯cs states. The results for 0+ and 1+ states with the angular momentum of the light component jl = 1/2 are consistent with the experimental values for Ds(2317) and Ds(2457), respectively.
