In this work, we consider the case of a strongly coupled dark/hidden sector, which extends
the Standard Model (SM) by adding an additional non-Abelian gauge group. These …

A bstract We examine the robustness of collider phenomenology predictions for a dark
sector scenario with QCD-like properties. Pair production of dark quarks at the LHC can …

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 …

A bstract This paper proposes a new search program for dark sector parton showers at the
Large Hadron Collider (LHC). These signatures arise in theories characterized by strong …

A bstract We study confining dark sectors where the lightest hadrons are glueballs. Such
models can provide viable dark matter candidates and appear in some neutral naturalness …

In an SU (N c) gauge theory with zero light quark flavors N f= 0, the only hadronic states that
form below the confinement scale are composite gluon states called glueballs. These …

A bstract We study the cosmology and LHC phenomenology of a consistent strongly
interacting dark sector coupled to Standard Model particles through a generic vector …

Semi-visible jets arise in strongly interacting dark sectors, where parton evolution includes
dark sector emissions, resulting in jets overlapping with missing transverse momentum. The …

Confining dark sectors at the GeV scale can lead to novel collider signatures including those
termed emerging jets with large numbers of displaced vertices. The triggers at the LHC …

This white paper discusses the current landscape and prospects for experiments sensitive to
particle dark matter processes producing photons and cosmic rays. Much of the gamma-ray …
