This file contains the result of the evaluation of the Feynman diagrams discussed in arXiv:1206.7087

In what follows b1= d a1/dt, c1= d b1/dt, etc... and symmetry and combinatorial factors are already included. To get the results reported in the paper, one has to sum the diagrams and perform several integrations by parts.

We remind to the paper for other notations and conventions.
