Description
ZH at LO without ISR:
good agreement for the cross section at the level of permil for Madgraph, Whizard and Sherpa as shown in the attached file. However the agreement between Madgraph and is even better at 0.1 permil. Are we initializing all generators (in particular sherpa) correctly with the same constants (MW, MZ, GFermi?
To generate the inputs:
