摘　　要：We parameterize the vertexes ΣQ([1])*QK* and ([1])'QΣ*QK* with three tensor structures due to Lorentz invariance,and calculate the corresponding three coupling constants within light-cone QCD sum rules.We then obtain their numerical values taking into account all the uncertainties of the relevant parameters.
