Madgraph5 simulation of a simplified model of Zprime with dijets and lepton decays of W/Z. Interference effects are included. Pythia8 was used to shower events. LHAPDF6:NNPDF23_lo_as_0130_qed. The sample was created using the Pythia8 tune Tune:pp = 14 similar to ATLAS.

Note

These files were created for validation of a Dark Matter model for an ATLAS analysis in the exotic group. A1/A2 refers to the two sets of coupling parameters.

A1: g_q = 0.25, g_l = 0
A2: g_q = 0.1, g_l = 0.1

There are 25k events for each mass point, the first four mass points for A1 are split into two files, one with 20k events (ending with "_1"), and 5k events (ending with "_2").

generate p p > y1 l v, y1 > j j
add process p p > y1 l l, y1 > j j

with bwcutoff=100 which effectively made it so that the y1 > j j decay can happen for offshell y1.
