Abstract We explore the phenomenology of Elastically Decoupling Relic (ELDER) dark matter. ELDER is a thermal relic whose present density is determined primarily by the cross-section of its elastic scattering off Standard Model (SM) particles. Assuming that this scattering is mediated by a kinetically mixed dark photon. we argue that the ELDER scenario makes robust predictions for ele... https://www.roneverhart.com/Bauhaus-Design-Stencil/
