WIMP Search in the Mono-Photon Channel at the International Linear Collider — •Moritz Habermehl1,2 and Jenny List1 — 1Deutsches Elektronen-Synchrotron DESY, Notkestraße 85, 22607 Hamburg — 2Universität Hamburg, Institut für Experimentalphysik, Luruper Chaussee 149, 22761 Hamburg
The International Linear Collider (ILC) is a planned electron-positron collider with √s tunable from 250 to 500 GeV, with a possible upgrade to 1 TeV. Besides precision measurements of the Higgs boson its physics goals comprise searches for physics beyond the Standard Model, e.g. searches for Dark Matter.
This collider search assumes the production of WIMPs in pairs. They are not visible in the detector but the energy carried away can be observed via an additional ("tag") particle. Photon emission from the initial state leads to the almost model independent signature: e+e−→χχγ. As this analysis tests couplings between WIMPs and leptons it is complementary to analogues searches at the LHC. A precise study is facilitated by the clean environment of lepton colliders with small systematics of electroweak backgrounds.
While the conceptual feasibility and the sensitivity reach of the ILC have been shown in the past, this talk focusses on the consequences for the detector design. The requirements for the central detector as well as for the instrumentation of the forward region will be discussed in the context of the ILD detector concept.
