Chaos & Complex Systems Seminar
Numerical modeling: Error, stability, and chaos
Time: 12:05 pm - 1:00 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.

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.
