I'm trying to get an analytic result, but can't seem to get it. Does anyone know of a lookup table or another way to get it? The Integral I need is of the form:
##\int d^{d}l \frac{1}{l^2 (l+q-p)^2 ((l-p)^2-m^2)}##
It should be convergent in 4 dimensions I believe, but without some regulators for the masses, which I DONT want, it might be best to work in "d" and absorb any divergences there.
This is equivalent to a passarino-veltman C0. I find results for other cases, but not this one. If I do it myself I can't find a favorable way to regulated the divergences that appear.
