The diagram for the ghost self-energy has already been considered in (87) and its PP is given by In the sequel we consider the diagrams Λ µνλ of the left-hand side of (103), with ghost loop, and photon loop, that have the same phase factors and, therefore, can be calculated analogously. Their PP contri- butions are PP[ p$_{µ}$γ $^{µνλ}$( p, q, k ) b ( p $^{2}$)] = e 2 16 π 2 1 ϵ [( k $^{2}$g λν − k $^{λ}$k$^{ν}$) − ( q $^{2}$g νλ − q $^{ν}$q$^{λ}$)] .
