D0
D0[p10, p12, p23, p30, p20, p13, m1^2, m2^2, m3^2, m4^2 ]
is the Passarino-Veltman D0 function. The convention for the arguments is that if the denominator of the integrand has the form ([q2−m12][(q+p1)2−m22][(q+p2)2−m32][(q+p3)2−m42]), the first six arguments of D0
are the scalar products p10=p12, p12=(p1−p2)2, p23=(p2−p3)2, p30=p32, p20=p22, p13=(p1−p3)2.
