- Chaos & Complex Systems Seminar
- Numerical modeling: Error, stability, and chaos
- Time: 12:05 pm
- Place: 4274 Chamberlin Hall (refreshments will be served)
- Speaker: George Hrabovsky, Madison Area Science and Technology
- Abstract: We rely heavily on approximation methods in science, as it is often the case that exact methods of solution are impossible with known mathematics. In this talk I will discuss the issues of approximation error, the stability of approximate solution methods, and the role of chaos in numerical modeling.
- Host: Clint Sprott
- Theory Seminar (High Energy/Cosmology)
- (Fundamental) Composite Models at the TeV scale
- Time: 3:30 pm
- Place: 5280 Chamberlin
- Speaker: Andrea Tesi, University of Chicago
- Abstract: New confining gauge theories offer a rich and robust phenomenology, mostly dictated by their accidental symmetries. For example, they naturally contain accidentally stable ‘baryon’ and/or ‘pion’ Dark Matter candidates. Moreover, if the strong sector enjoys chiral and custodial symmetries, it can offer a framework for Composite Higgs models, where the Higgs doublet is a partially-composite light ’pion’. I will discuss how this can be made consistent with the flavor sector of the SM and comment on the main LHC phenomenology both in direct and indirect searches.
