Abstract We parameterize the vertexes Σ_QΞ_Q^*K^* and Ξ'_QΣ_Q^*K^* 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.
