摘要We parameterize the vertexes ΣQΞQ*K* and Ξ'QΣQ*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.
