Problem for generating generate p p > t t~ w j QED=3 QCD=1 [QCD]

Asked by Meng-Ju Tsai on 2021-09-14

Hello Madgraph experts,

We are trying to produce ttW EW sample with 1j@NLO (with QCD NLO correction).

Here are how we did to generate the samples. The command works to produce the diagrams. However, when we did the `launch` step, we have issues failing several tests. I added the model "import model loop_sm-no_b_mass" but this doesn't work for me.

Do you have ideas on how I should do with the errors?

Thank you very much!

Cheers,
Meng-Ju

---------- Command we used ----------

```
set gauge unitary

import model loop_sm-no_b_mass
define p = g u c d s u~ c~ d~ s~
define j = g u c d s u~ c~ d~ s~
define w = w+ w-
define l+ = e+ mu+ ta+
define l- = e- mu- ta-
define vl = ve vm vt
define vl~ = ve~ vm~ vt~
define uc = u c
define uc~ = u~ c~
define ds = d s
define ds~ = d~ s~

generate p p > t t~ w j QED=3 QCD=1 [QCD]

output -f

launch
