Title: Direct Detection with Dark Mediators
Host: Ennio Salvioni
Room: 432
Abstract: In this talk I will discuss a topological modification of the dark matter/nucleus scattering for direct detection experiments. Instead of having a standard 2 to 2 scattering with contact operators, we look at a tree level 2 to 3 process, X N -> X N phi, with phi being a SM singlet carrying the same dark charge which stabilizes the DM. The interesting phenomenology from the setup motivates the study of the dark mediator Dark matter (dmDM). By focusing on a simple model that gives a sizable scattering cross section, we discuss the direct-detection consequences of this scenario and find that a heavy O(100 GeV) dmDM candidate fakes different O(10 GeV) standard WIMPs at different experiments. Various collider and astrophysical constraints will be addressed. A large portion of the allowed dmDM parameter space are detectable in future experiments, and the model have interesting applications in reconciling different types of DM experiments.

Title: Cosmic Axion Spin-precession Experiment
Host: Nemanja Kaloper
Room: 432
Abstract: We propose an experiment to search for QCD axion and axion-like-particle (ALP) dark matter. Nuclei that are interacting with the background axion dark matter acquire time-varying CP-odd nuclear moments such as an electric dipole moment. In analogy with nuclear magnetic resonance, these moments cause precession of nuclear spins in a material sample in the presence of a background electric field. This precession can be detected through high-precision magnetometry. With current techniques, this experiment has sensitivity to axion masses m_a <~ 10^(-9) eV, corresponding to theoretically well-motivated axion decay constants f_a >~ 10^16 GeV. With improved magnetometry, this experiment could ultimately cover the entire range of masses m_a <~ 10^(-6) eV, just beyond the region accessible to current axion searches.
