Abstract:

Although the discovery of the Higgs boson in 2012 was a very exciting moment for high energy physics, there are still a range of questions that remain unanswered, such as the heirarchy problem. Many theories of new physics which seek to answer these questions postulate the existence of new particles. With the start of Run 2 at the Large Hadron Collider at CERN, the record setting center-of-mass energy of 13 TeV has helped to improve our ability to explore these new physics models. In this talk, I will present a search for heavy right-handed resonances decaying to a top and bottom quark, performed using 2.2/fb of data collected by the Compact Muon Solenoid experiment in 2015.

No significant excess of events with respect to the predicted Standard Model backgrounds is observed, and resonance masses less than 2.38 TeV are excluded. This the most stringent exclusion to date in this channel, and the first search in the channel performed at 13 TeV.
