Events on Friday, October 18th, 2013
- Theory Seminar (High Energy/Cosmology)
- Neutrino Advances and Developments in Finite Group Models
- Time: 2:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: David A. Eby, Vanderbilt University
- Abstract: Neutrino discoveries over the last decade and a half have provided the first definite observation of particle physics beyond the standard model. The ramifications of these results are continuing to impact the theory community, as its members struggle to adapt old models and develop new ones. Finite group models have been particularly successful at providing explanations for new neutrino behavior. Our work, titled Binary Tetrahedral Flavor Symmetry or the TaEuroTM Model, endeavors to bridge the quark and lepton families in a single coherent system by means of additional Higgs-like particles. This theory provides testable predictions for neutrino mixing, quark mixing, and dark matter. Where possible, we evaluate these predictions against current experimental evidence and find agreement with the atmospheric and reactor neutrino mixing angles, an accurate prediction of the Cabibbo angle, and a dark matter candidate outside of current limits. Taken together, we believe these results speak to the promise of finite groups and flavor symmetries to accurately approximate nature.
- Physics Department Colloquium
- Search for Higgs Boson Decays into Invisible Particles at the LHC
- Time: 3:30 pm
- Place: 2241 Chamberlin Hall (coffee at 4:30 pm)
- Speaker: Ketevi Assamagan, Brookhaven National Lab
- Abstract: In this talk, we will discuss whether the Higgs-like particle discovered with a mass around 125 GeV has a significant decay into invisible (undetected) particles. We will also discuss whether there may be other Higgs-like bosons at different masses with significant decays into invisible final state.
