A search for the pair production of heavy fermionic partners of the top quark with charge 5/3 (X5/3 ) is performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The data sample analyzed corresponds to an integrated luminosity of 35.9 fb−1 . The X5/3 quark is assumed always to decay into a
