Description:
The Dark pions (emerging jets) model with the settings as for the CMS publication JHEP 02 (2019) 179 (https://arxiv.org/abs/1810.10069).

The files use the A14 ATLAS tune with NNPDF23_lo_as_0130_qed. The luminosity was estimated from the first file and is not accurate for the entire dataset. All parameter settings and cross sections are included in the logfiles inside separate ProMC files.

The emerging jet model is described in:
  • Y. Bai and P. Schwaller, “Scale of dark QCD”,Phys. Rev. D89(2014) 063522,doi:10.1103/PhysRevD.89.063522,arXiv:1306.4676
  • P. Schwaller, D.Stolarski, and A. Weiler, “Emerging jets”,JHEP05(2015) 59,doi:10.1007/JHEP05(2015)059,arXiv:1502.05409.
Evens are created using a fixed dark pion mass of 5 GeV and different decay length (ctau). Each file has the substring "_mXX_ctYY" where XX and YY indicate the mediator mass and the decay length (in mm) of dark pion with the mass 5 GeV (fixed).
