Description:

Title: Is the 3rd generation special? Measurements in top events at the LHC

 

Speaker: Jacob Linacre, FNAL
 

Abstract: The large mass of the top quark and its expected uniquely strong coupling to the Higgs boson suggest a connection between the third generation and the mechanism of electroweak symmetry breaking. New physics in this mechanism is likely to modify the properties of top quark events from the standard model (SM) expectations, with top partners a common prediction to resolve the hierarchy problem. Furthermore, the top quark is the only quark that decays before hadronising, which makes precision top quark properties measurements an ideal laboratory to test perturbative QCD and probe for new physics either in underlying direct production modes or from interference effects from new physics at higher mass scales. In this presentation I focus on the search for a top super-partner and precision spin measurements in events with a top quark and antiquark.
