Alexander Wijangco (University of California Irvine)05/05/2014, 14:00We present on the role which complementarity plays in dark matter modeling. Experimental dark matter results provide a wealth of information for dark matter modeling in terms of both positive and negative results. The utilization of input from a variety of complementary experimental probes can provide useful insight into the parameter space of the model by offering new bounds upon the...Go to contribution page

Dr Brooks Thomas (Carleton University)05/05/2014, 14:15Dark-matter complementarity is a reflection of the fact that even in single-component theories of dark matter, a single Lagrangian operator often contributes to a variety of physical processes including production at colliders, elastic scattering at direct-detection experiments, and dark-matter annihilation. However, in multi-component theories of dark matter, a single such operator can also...Go to contribution page

Mr Jeffrey Hutchinson (UC Davis)05/05/2014, 14:30Null results from collider and direct detection searches constrain dark matter candidates. We analyze these constraints in the context of minimal extensions to the standard model. The "WIMP miracle" for the relic abundance of thermal dark matter motivates models of weak scale dark matter with renormalizable couplings to standard model particles. We study minimal extensions to the standard...Go to contribution page

Patrick Stengel (University of Hawaii)05/05/2014, 14:45We investigate constraints on the properties of light dark matter which can be obtained from analysis of invisible quarkonium decays at high intensity electron-positron colliders in the framework of a low energy effective field theory. A matrix element analysis of all interaction structures pertinent for these bound state decays allows for a model independent calculation of associated dark...Go to contribution page

Andrea Massari (S)05/05/2014, 15:00The Fermi γ-ray Space Telescope has observed the sky since 2008. Dark matter annihilations or decays contribute to the measured diffuse gamma-ray background flux. We present conservative bounds on annihilation cross section or decay lifetime. We consider DM annihilation/decay into 12 different Standard Model final states, 3 DM density profiles and 2 GeV < m_{DM} < 10 TeV , performing no...Go to contribution page

Mr Sungwoo Hong (University of Maryland-College Park)05/05/2014, 15:15We investigate the prospects for detecting a hidden sector at an e+ e− collider. The hidden sector is assumed to be composed of invisible particles that carry no charges under the Standard Model gauge interactions, and whose primary interactions with ordinary matter are through the Higgs portal. We consider both the cases when the decays of an on-shell Higgs into a pair of hidden...Go to contribution page

Daniel Salmon05/05/2014, 15:30We will describe the construction of a new kinematical variable that can fully reconstruct the absolute value and partially reconstruct the sign of the angular distribution in the center of momentum system of a decaying mother particle. This will then be used to illustrate a method by which the spin of a pair produced dark matter candidate at the International Linear Collider (ILC) can be...Go to contribution page

Jianghao Yu (Univ. of Texas at Austin)05/05/2014, 15:45I will talk about the mass measurements for dark matter and its mother particles appearing in decay chains can be improved by determining the boundary of the available phase space in its full dimensionality rather than by using one-dimensional kinematic features for each stage of the cascade decay. This is demonstrated for the case of one particle decaying to three visible and one invisible...Go to contribution page
