generate ttbar with one loop weak boson correction

Asked by Winston

Hi experts,
How can I generate ttbar( p p > t t~)samples and consider one loop weak boson correction, which includes Z boson and Higgs boson.
I know it should use model named "loop_qcd_qed_sm", but I don't know how to take the loop correction of Z and higgs boson into consideration. Can you give me details with step by step. thank you.

best regards,
Winston

Hi,

For ElectroWeak correction we only support fixed order NLO computation.
This mode does not allow to generate sample (since you need NLO+PS mode for that).

Note that The ElectroWeak correction is only supported by MG5aMC version 3 which is still in beta.

Cheers,

Olivier
