| الوصف: | We present the first results on searches for new massive resonances decaying to a top-antitop quark ($t\bar{t}$) pair with the CMS detector at the LHC in proton-proton collisions with a center of mass energy of $\sqrt{s}=13~\mathrm{TeV}$. The data set considered corresponds to an integrated luminosity of $2.6~\mathrm{fb}^{-1}$ recorded during the the first year of the LHC Run-2. Searches are performed by measuring the invariant mass distribution of the $t\bar{t}$ system in semileptonic and fully-hadronic final states. Dedicated techniques are used to identify the decay of highly-boosted top quarks in order to maximize the analyses' sensitivity for $t\bar{t}$ resonances with a mass above the TeV scale. No significant excess is observed in the data compared to the expected SM background and exclusion limits are set on the cross section of a $t\bar{t}$ resonance in various new physics scenarios.
