Calculation of Tensor Susceptibility Beyond Rainbow-Ladder Approximation

In this paper, we extend the calculation of tensor vacuum susceptibility in the rainbow-ladder approximation of the Dyson–Schwinger (DS) approach in Shi et al. (Phys Lett B 639:248, 2006) to that of employing the Ball–Chiu (BC) vertex. The dressing effect of the quark-gluon vertex on the tensor vacu...

Description
Summary:In this paper, we extend the calculation of tensor vacuum susceptibility in the rainbow-ladder approximation of the Dyson–Schwinger (DS) approach in Shi et al. (Phys Lett B 639:248, 2006) to that of employing the Ball–Chiu (BC) vertex. The dressing effect of the quark-gluon vertex on the tensor vacuum susceptibility is investigated. Our results show that compared with its rainbow-ladder approximation value, the tensor vacuum susceptibility obtained in the BC vertex approximation is reduced by about 10%. This shows that the dressing effect of the quark-gluon vertex is not large in the calculation of the tensor vacuum susceptibility in the DS approach.
