Sorry, another quick question. I still don't understand if it's possible with OneLoop to have a result in D dimensions. It always gives me the result in 4 dimensions.

For example, if I write:

-I/Pi^2*OneLoop[k,FeynAmpDenominator[PD[k, I*m], PD[k, 0]] (-PolarizationSum[mu, nu, k, Dimension -> D])*ScalarProduct[k, k, Dimension -> D]], Dimension -> D]

it gives me:

3/4 Subscript[A, 0](-m^2) g^(mu nu)+1/8 m^2 g^(mu nu)

Instead, I would like to obtain a result in D dimension, like:

(D-1)/D Subscript[A, 0](-m^2) g^(mu nu)

Is that possible?

Thank you very much.

Pietro
