The problem is there must be one gauge parameter when I have got one gauge boson but there are a couple of different parameters and OneLoop[] does not work because of them ,I suspect (as I have checked the rest of the code). For example self energy bubble of a scalar I have in my model appears like this:
(2^(1-D) \[Pi]^(-D/2) g^2)/(q^2-ms^2 Subscript[\[Xi], S(Gen3)])
