| Figure 5. The nonfactorizable Feynman diagrams in the color space for the lowest order contributions for the current Jccc(x), where the solid lines and dashed lines represent the light quarks and heavy quarks, respectively, the other diagrams obtained by interchanging of the three vertexes at the point 0 or x are implied. |
