I have used OneLoop function, the result is expressed involving B0[pp,0,0].
I know B0 is the scalar integral of Passarino-Veltman reduction, but I wonder can also B0 be reduced to some explicit form, just like terms of log, gamma(Eulers constant) such that?
Are there some useful function to deal with two-loop amplitudes?
pre-Thanks!
