Top physics beyond the standard model: prospects at CSM

Precise studies of the top quark sector will be performed in the Lhc in order to test the standard model and search for new physics. The top-quark sector at the Lhc opens a very rich region to look for new phenomena. Searches beyond the standard model include new top quark decays and top quarks in resonant production. In the latter, a good observable to carry on a model-independent search is the top pair invariant mass. A special reconstruction procedure is needed for the case of heavy resonance decaying into very high-pT top jets. CMS is developing tools to improve the reconstruction of these highly boosted top jets and studying the discovery potential for new physics in the top quark sector. A brief review of these studies is given in this paper.
