Populating high pT regions ...

Asked by Shankha Banerjee

Hello,

I am generating SM and SMEFT samples at NLO QCD for the process p p > w+ w- [QCD]. Now, I need to populate the high pT, mll, etc. regimes. Even with 2M events, I am not reaching the desired accuracy. Is there a way to populate the high pT regimes? I know that putting a hard mWW cut in the cuts.f file might achieve something similar but I do not know the exact correlation between pTl1, pTl2, mll with mWW.

Any help would be great.

Thanks.

Best regards,

Shankha.

Hi,

My typical recomendation here is to do two sample
1) a sample without any cut
2) a sample with "hard" cut

and then from the sample generated in 1 veto all events that pass the cut in "2".
Like that you are sure that you never have bias.

Cheers,

Olivier
