148. Leptonically-flavored Dark Matter

Jennifer Kile (U)

We consider the possibility that dark matter and the SM leptons share a common flavor interaction mediated by heavy flavor gauge bosons. Constraints on this scenario are then obtained from both dark matter and flavor observables, such as the DM relic density, direct detection, collider constraints, and g-2 of the muon. We then consider the consequences for future experiments, including LHC.

48. Leptophilic Dark Matter and the Magnetic Moment of the Muon

Christopher Verhaaren (U)

We consider renormalizable theories such that the scattering of dark matter off leptons arises at tree level, but scattering off nuclei only arises at loop. In this framework, the various dark matter candidates can be classified by their spins and by the forms of their interactions with leptons. We determine the corrections to the anomalous magnetic moment of the muon that arise from these...

143. Searching for Sub-GeV Dark Matter at Fixed Target Neutrino Experiments

Mr Patrick deNiverville (University of Victoria)

06/05/2014, 17:00

Low mass dark matter theories, if produced as a thermal relic in the early universe, must be accompanied by light mediators in order to obtain the dark matter abundance observed in the present day universe. These light mediators in turn provide a channel for the production of dark matter at high intensity fixed target neutrino experiments, producing a relativistic dark matter beam, which could...

147. Decaying Dark Matter and IceCube TeV-PeV neutrinos

Ran Lu

06/05/2014, 17:15

I will talk about the IceCube TeV-PeV neutrino excess and theoretical proposals postdict the observation, emphasis on potential connection with dark matter.

24. Predicting the Mass of the Dark Matter Particle

Prof. Stephen Barr (University of Delaware)

06/05/2014, 17:30

Asymmetric dark matter and baryonic matter can be "co-generated" by non-Standard-Model sphaleron processes in grand unified models. Such models can give precise predictions of the number density and thus mass of the dark matter particle.

74. Parallel Universe, Dark Matter and Invisible Higgs Decays

Prof. S. Nandi (Oklahoma State University)

06/05/2014, 17:45

The existence of the dark matter with amount about five times the ordinary matter is now well established. There are now many candidates for this dark matter. However, dark matter could be just like the ordinary matter in a parallel universe. If both universes are described by a non-abelian gauge symmetries, then there will be no kinetic mixing between the ordinary photon and the dark photon,...

55. Dark Sector Mass Relations from RG Focusing

Jack Kearney (University of Michigan)

06/05/2014, 18:00

Dark sector mass relations, such as those which permit near-threshold or near-resonance annihilation in the early universe, could arise due to IR-attractive ratios in renormalization group equations. Achieving a particular ratio requires specific dark matter gauge charges or interactions, leading to predictions about the dark matter properties. Furthermore, additional states with masses...

208. Searches for dark matter and extra dimensions with the ATLAS detector

Mr Chase Shimmin (UC Irvine)

06/05/2014, 18:15

Different approaches to finding evidence for dark matter at the LHC are presented. These include searches for events with large missing transverse momentum and a single jet, photon or W/Z boson. Searches for hidden sectors in events with long-lived particles resulting in displaced hadronic vertices or lepton-jet signatures are also reported. Finally, studies sensitive to the presence of...
