Description
Cesare Cazzaniga, Alessandro Russo, Emre Sitti, and Annapaola de Cosa propose a new collider signature for hidden dark sectors. Their 2024 letter models a dark copy of the strong force, whose bound states can form jets that are partly visible. A heavy carrier particle would let normal quarks spawn dark quarks in proton clashes.
Some dark bound states decay back to normal quarks, while others decay to light. That split yields jets rich in loose photons, a pattern current searches miss. Loose photons fail photon cuts, and high light share fails jet cuts. The team drops the light-share cut and trains a deep network to tag the odd jets. They estimate a top-energy reach for discovery with past collider data.
