- Theory Seminar (High Energy/Cosmology)
- Constraining Dark Matter with Background Light
- Time: 2:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Sam McDermott, University of Michigan
- Abstract: Photons are generic in final states of dark matter annihilation or decay, and a wide range of X-ray and gamma ray observations are available to constrain broad classes of dark matter models. In the first part of the talk I will survey some robust bounds derived in the context of light decaying dark matter. These bounds are applicable in complete generality, making no assumptions about background models or underlying astrophysics, and they can be applied both in model dependent and model independent contexts. In the latter part of the talk, I will discuss some work in progress that focuses on bounds on annihilating dark matter from the isotropic gamma ray background.
- Physics Department Colloquium
- Higgs Boson Discovery: What's Next?
- Time: 3:30 pm
- Place: 2241 Chamberlin Hall (coffee at 4:30 pm)
- Speaker: Marcela Carena, Fermilab & Kavli Institute for Cosmological Physics
- Abstract: The ATLAS and CMS experiments at the Large Hadron Collider at CERN have recently discovered a new particle, that has properties consistent with those of a Higgs boson associated with the mechanism that generates the mass of all the fundamental particles in nature. Such a discovery poses questions that may point towards new physics beyond the Standard Model of particle physics, and may shed light to some of the most fundamental questions of science: The unication of all the forces; the explanation of the matter-antimatter asymmetry of the universe; and the nature and origin of dark matter. I will discuss the interpretation of the latest experimental results relevant for Higgs physics both within the Standard Model and in its extension through an enhanced symmetry of nature, called "Supersymmetry".
