Computation fails when using [LOonly=QCD]
Hi,
I am trying to generate the following process:
generate p p > t t t~ t~ NP^2==2 QCD<=4 QED<=4 YT<=4
in smeftatnlo (I adapted the model such that the Yukawa is explicit, hence YT).
Running this process as shown above is perfectly fine and it generates ~1000 independent diagrams. However, running the exact same process with [LOonly=QCD] or [LOonly=all] results in the computation failing. I checked the end of the log file in the sub-process directories, and this is what it reads:
"Too many gridpacks to keep track off"
--> Is there a way around that?
Another thing I noted that with this syntax is that more diagrams are generated (~2000 independent) compared to the normal generation,
--> is that understood? (I was not able to compare the cross-sections since the computation never succeeded)
Even though I want to study this process at LO, the reason I use the [LOonly=QCD] syntax is because I want to do a Fixed Order HwU Analysis (and separate smeft orders, etc.) and this is the only way, as far as I know, by which I can do that.
Your help is much appreciated.
Best,
Hesham
