Problem with ggF
Dear developers,
I want to calculate the LO contribution to gluon fusion by means of the madloop library. I used the command
generate p p > h [QCD],
which generates the expected process and diagrams. However, when I try to create an output I get the following error
Command "output GGF" interrupted with error:
TypeError : unsupported operand type(s) for -: 'int' and 'NoneType'
The debug file shows the following:
