Description
Dark matter produced via a strongly-coupled hidden sector can produce a wide array of signatures in detectors. In particular, in a model where the standard model couples to the dark sector via a leptophobic Z' mediator, the decay of the Z' mediator would yield jets that consist of partly visible and dark matter. The signature in a detector of such a 'semi-visible jet' is a jet aligned with missing transverse energy - a signature that is explicitly vetoed in most dark matter searches. CMS has recently published a search for semi-visible jets, the first of its kind at hadron colliders.
