Search for top quark partners with charge 5/3 in proton-proton collisions at √s=13 TeV

A search for the production of heavy partners of the top quark with charge 5/3 (X5/3 ) decaying into a top quark and a W boson is performed with a data sample corresponding to an integrated luminosity of 2.3 fb−1 , collected in proton-proton collisions at a center-of-mass energy of 13 TeV with...
