SMEFTNLO reweighting problem. KeyError: (((-3, 4), (-6, 6, 24)), 'V')

Asked by Reza Goldouzian

Dear Experts,

I am trying to generate ttW process with EFT vertices at NLO. I am going to include weights for various combination of EFT coupling in my sample. My process card is like

import model SMEFTatNLO_U2_2_U3_3_cG_4F_LO_UFO-NLO
define j = p
define p = 21 2 4 1 3 -2 -4 -1 -3 5 -5
define WW = w+ w-
generate p p > t t~ WW QCD=2 QED=1 NP=2 [QCD]
output ttW_SMEFTNLOQED1_v1 -nojpeg

everything works when I do reweighting at LO. But for NLO reweighting, I see the following error
KeyError : (((-3, 4), (-6, 6, 24)), 'V')

I do not know what is wrong in my NLO reweighting procedure.

Best regards,

Reza

Can you create a bug report and attach to it
1) Your UFO model
2) the lhe file that you try to reweight
3) the reweight_card

Thanks,

Olivier
