Perturbative benchmark models for a dark shower search program

We provide five benchmark hidden valley models with perturbative parton showers, which span a wide range of dark shower phenomenology. We consider production through an s-channel, heavy mediator, which can be identified with the SM Higgs. By assuming a set of well-motivated decay portals, one can moreover fix both the branching ratios of the dark mesons and set a lower bound on their lifetime. We provide a public PYTHON tool which can be used to generate self-consistent PYTHIA 8 cards for our benchmark models.

Automated summary

Researchers provide five benchmark hidden valley models with perturbative parton showers, and offer a public PYTHON tool to generate self-consistent PYTHIA 8 cards for these benchmark models.
