Search for top quark partners with charge 5/3 at $\sqrt{s}=13$ TeV

A search for the production of heavy partners of the top quark with charge 5/3 is presented. The data sample corresponds to an integrated luminosity of 2.2 fb$^{-1}$ and was collected at a center of mass energy of $\sqrt{s} = 13$ TeV by the CMS experiment at the Large Hadron Collider. The search is performed using events with two different signatures: same-sign dileptons as well as a semi-leptonic final state. No significant excess is observed in the data above the expected standard model background. Upper bounds at the 95$\%$ confidence level are set on the production cross section of heavy top quark partners.
