Searches for Resonances decaying into top quarks

header

09 June 2012

The top quark is as heavy as a gold atom. Unusually heavy for an elementary particle. For that reason, it may play a special role in physics beyond the Standard Model that we are trying to identify. We (and our local collaborators from SFU and UBC) searched for a di-top resonance for the first time in the channel where both W bosons originating from the top quark decay into an electron or a muon together with their corresponding neutrino. In the absence of a signal we set limits on the production of Kaluza-Klein Gluons, that appear in extra dimensional model, with masses greater than 1.1 TeV. Details can be found here.
