Dear Vladyslav,

thank you so much for all the help.

I come to you now with another question. Feyncalc thinks that B0(0,0,0)
is zero (where B0 is the Passarino-Veltman usual function). But the
truth is that B0(0,0,0) is doubly divergent: infrared (because we have
ln 0) and UV (because of the 1/\epsilon divergence).

So what's happening here? How come does Feyncalc think B0(0,0,0)=0?

Best regards,
Duarte
