Composite Higgs model with Zprime as described in the article. Events are created using MG5 with Pythia8 shower.

Technical details

MG5 LHE files are included. They contain parameters used for Pythia8. The files use the A14 ATLAS tune with NNPDF23_lo_as_0130_qed. All parameter settings are included in the logfiles inside separate the ProMC files. Mass of Zprime is given by the number after "mZp" (in GeV). The mass of composite Higgs is given by the number after "mL". Use LHE files to check decay modes. When the file name has the name "auto", this means the width is set to "auto width". Otherwise, the width is fixed to narrow width approximation. MG5 parameters:

set default_unset_couplings 99
set group_subprocesses Auto

set loop_optimized_output True
set low_mem_multicore_nlo_generation False
set loop_color_flows False
set gauge unitary
set complex_mass_scheme False
set max_npoint_for_channel 0
