In HQET(Heavy Quark Effective Theory) we come across may loop integrals where one of the propagators is v.k rather than k.k-m^2. I was wondering if there is a way for OneLoop to handle these integrals? An example would be:

AMP = FAD[{q,m}] 1/(ScalarProduct[q,v]-X);

Gives 0, but the answer by hand is not zero. (X here is just some constant to displace the propagator.)

The actual result can be found a number of places:
( Equation # 407)

Is there a way to input that second part so OneLoop can calculate it?
