| Abstract: | A new approach for calculating vacuum susceptibilities from an effective quark-quark interaction model is derived. As a special case, the vector vacuum susceptibility is calculated. A comparison with the results of the previous approaches is given. |
| Keywords: | QCD vacuum vector vacuum susceptibility global color symmetry model |
