High-Energy Physics & RIKEN Theory Seminar

"Flavour Symmetric Sectors and Collider Physics"

Presented by Michael Trott, Perimeter Institute for Theoretical Physics

Wednesday, November 9, 2011, 2:00 pm — Small Seminar Room, Bldg. 510

We discuss the phenomenology of effective field theories with new scalar or vector representations of the Standard Model quark flavor symmetry group, allowing for large (aligned) flavor breaking involving the third generation. Such field content can have a relatively low mass scale ≤TeV and O(1) couplings to quarks, while being consistent with both flavor violating and flavor diagonal constraints. These theories therefore have the potential for early discovery at LHC, and provide a flavor safe "tool box" for addressing anomalies at colliders and low energy experiments. We catalogue the possible flavor symmetric representations, and consider applications to the anomalous Tevatron t-tbar forward backward asymmetry and Bs mixing measurements. More general collider signatures and constraints on flavor symmetric models are also discussed.
