(Anti q)q 3P-0 condensation under an modified r2 potential

The authors have modified the r2 correlated kernel. Under this modification, the kernel remains V03r2δ(τ) at small r and when r is large enough, it tends to be Aδ(τ), where A is a constant. Thus, the kernel no longer corresponds to a complete confinement potential. By solving the Gap equation, the authors found that the contribution of the modification to quark-antiquark condensation is obvious, though the main results of vacuum condensation remain
