Matching in Pythia 8 with LHE files

Asked by ushoshi maitra

Hi,
     I need to generate t t~ + nj (n <= 2) for my analysis. I'm working in Pythia 8. Is there any option for matching in Pythia 8 after generating the process in MG5? I'm doing the following :
In the madgraph level:
generate p p > t t~ @0
add process p p > t t~ @1
add process p p > t t~ @2
Then in the run_card.dat:
ickkw = 1
xqcut = 20
drjj = 0.001
I'm then interfacing this LHE file to my pythia 8 code. By this procedure if I start with 20000 events I'm ending up with 2500 events. Is this procedure correct? Also is there any way to check the matching scheme there. Can I see the distribution for differential Jet rates there?

Thanks in advance!

Best,

Ushoshi

Hi,

The full support of the matching with Pythia8 is not yet available.
Now basically all the functions are present and we need to automate the interface between PY8 and mG5_amc.

Cheers,

Olivier
