Search for pair production of excited top quarks in the lepton + jets final state
(2014-06-19)
A search is performed for pair-produced spin-3/2 excited top quarks (t∗t¯∗), each decaying to a top quark and a gluon. The search uses data collected with the CMS detector from pp collisions at a center-of-mass energy of ...
