DJR plot

[semlalisouad]

Dear MAdanalysis team,

I used MG to generate events for DY process with 4jets (pp > mu+mu- jj b b~) with MLM, with
qcut = 19, xqcut = 10, ickkw =1.
Please find attached the DY_banner.txt.

Merging scale, Cross-section [pb] , MC uncertainty [pb]
19, 2.167654e+00, 1.10e-02
28.5, 8.429754e-01, 6.86e-03
38, 4.335304e-01, 4.92e-03

I am trying to generate DJR plots using madanalysis, but the plots are empty.
import /home/semlali/MC/MG5_aMC_v2_9_5/DY2b2jets/Events/run_05/DY_pythia8_events.hepmc.gz
set main.merging.check = true
set main.merging.ma5_mode = true
set main.merging.njets = 4
Am I missing something?

Many thanks for your help

Hi @semlalisouad i only see one sample in your event, to work with djr you need events with different jet multiplicities and i don’t mean the ones generated during shower. Generally we generate 0, 1, 2 jet events and plot djr distributions.

Hi Jack,

Thank you for your reply. I also tried to generate the process up to 4-jets, but even in that case, the DJR plots are empty.
Please find attached the banner.txt (0,1,2,3,4 jets).

Thank you for your help.
