| Description | Speaker: Christiane Scherb Title: Co-decaying dark matter in a Hidden Valley Room: 3024 Host: John Terning Abstract: Dark sectors, for example Hidden Valley models, are an interesting alternative to WIMPs. Hidden Valley models extend the SM by adding a non-Abelian gauge group and light fermions charged under it. In most Hidden Valley scenarios the dark matter candidate is a dark baryon. In this talk I discuss a setup in which the lightest dark mesons, called dark pions, are the dark matter candidate. In such a setup the observed relic dark matter abundance is obtained through co-decaying freeze-out. The resulting dark matter parameter space can be probed through the rich collider phenomenology of such models. However, collider probes of Hidden Valley models depend on the dark hadronization model. I show how the Lund Jet Plane can be used to construct hadronization model independent variables for dark sector searches. |
