Uncovering tau leptons-enriched semi-visible jets at the LHC.

This Letter proposes a new signature for confining dark sectors at the Large Hadron Collider. Under the assumption of a QCD-like hidden sector, hadronic jets containing stable dark bound states could manifest in proton-proton collisions. We present a simplified model with a boson yielding the production of jets made up of dark bound states and subsequently leading to the decays of those that are unstable to leptons and Standard Model quarks.
