Most probably I missed a commutator in the interaction term, which accounts for an extra term in the transformation of G. More important, as you suggested I should keep everything to first order, that should be the way to transform correctly the field strength tensor. I still don't know how exactly, but now I should be on the right way... Dropping the problem now for lack of time, but at least I saw the light at the end of the tunnel. Thank you. | |

expanded on the expansion
