Amplitudes in Four dimentional helicity scheme(FDH) and 'tHooft-Veltman scheme (HV).

Asked by Biswajit Das

Dear Sir,

I am checking my results with Madgraph in individual(and total) diagrams for the process H-> WW*. I filter the diagram number in loop_diagram_generation.py file and generate individual diagrams. I do have agreements on pole pieces but having problems with finite pieces. I think the discrepancies are coming from different regularization schemes. Can you please tell me how can I compute amplitudes(individual or total) in HV or FDH in Madgraph?

Thanks,
Biswajit Das,
