Simulated semivisible jets of the "Aachen" model

Dataset published with "Semi-visible jets, energy-based models, and self-supervision", Favaro L. et al.

It consist of a QCD dijets background file "qcd_constit.h5" and a signal file "aachen_constit.h5". The signal model has been proposed in "Strongly interacting dark sectors in the early Universe and at the LHC through a simplified portal", Bernreuther E. et al. 

The signal model has a dark mediator with mass m_Z'=2TeV and dark quarks with mass m_qd=500MeV charged under dark SU(3)_d. The hadronization of the dark sector consist of dark pions with mass m_pi=4GeV and dark rhos with mass m_rho=5GeV.

Simulation:

• Madgraph + Pythia + Delphes simulation;
• (E, px, py, pz) of the first 200 constituents, pT ordered;
• most jets have less than 70 constituents, the remaining ones are zero-padded;
• Fastjet reconstructed fat jets using anti-kt algorithm with R=0.8;
• kinematic cuts: 100<pT<300, |\eta<2| ;
• semivisible jets are matched to the parton level dark quark;
• pheno parameters: invisible fraction r_inv=0.75, m_pi=4GeV, m_rho=5GeV.
