HEP Seminar Radboud Universiteit Nijmegen: Exploring new physics in the Top quark sector using Beyond-Two-Generations Quarks with the Compact Muon Solenoid

In many models of physics beyond the Standard model the coupling of new physics to third generation quarks is enhanced or signatures are expected that mimic top production. I will present a review of mostly non-MSSM-inspired searches for new physics beyond the standard model in final states containing top quarks or bottom quarks performed by the CMS experiment. Many of these techniques used have solid roots in precision measurements of the standard model, and applying these
techniques from measurements to searches has opened a rich and varied searches program in the CMS experiment. Examples include searches for heavy gauge bosons, excited quarks, sequential and vector-like top quark partners. The analyses span a range of final states, from multi-leptonic to entirely hadronic, and many use convoluted analysis techniques to reconstruct the highly boosted final states that are created in these topologies.
I will focus on the most recent results, using data collected with the CMS experiment in proton-proton collisions at the LHC at a centre-of-mass energy of 8 TeV.
