I will describe a new collider object we have termed emerging jets.
These can arise when there is a confining dark sector connected to the Standard Model by a TeV scale mediator, a scenario that is well motivated by dark matter considerations. The signature of an emerging jet is O(10) displaced vertices inside the jet each with different impact parameter, and a small number of prompt tracks. I will describe strategies that can be used to discover emerging jets even if they have very small cross sections.
