Hi. I seem to be having some issues getting the arguments to PaVe functions to change their arguments. Given the input:
FCClearScalarProducts[];
ScalarProduct[k1, k1] = SMP[“m_W”]^2;
amp = SPD[k1, k1] FAD[{q}, {q - k1, m}, {q, m}];
int = TID[amp, q];
int;
% // ExpandScalarProduct;
% // ToPaVe[#, q] &
FCClearScalarProducts[];
ScalarProduct[k1, k1] = SMP[“m_Z”]^2;
amp = SPD[k1, k1] FAD[{q}, {q - k1, m}, {q, m}];
int = TID[amp, q];
int;
% // ExpandScalarProduct;
% // ToPaVe[#, q] &
The output is:
(i \pi^2 mW^2)/m^2 (B0(mW^2, m^2, m^2) - B0(mW^2, 0, m^2))
(i \pi^2 mZ^2)/m^2 (B0(mW^2, m^2, m^2) - B0(mW^2, 0, m^2))
The issue is FCClearScalarProducts appears to change the k1^2 to mZ^2 in the coefficient of the function, but not in the argument of the PaVe integral. I was wondering if there was any way to clear this manually? Thanks so much for your time!
