Abstract: (PoS)
A search for new phenomena in ttˉt\bar{t} final states with additional heavy-flavour jets has been carried out using 13.2 fb1^{-1} of data in pppp collisions at s=13\sqrt s = 13 TeV with the ATLAS detector at the LHC. The search targets a variety of signals, including the pair production of vector-like top quarks; four-top-quark production in several new physics scenarios. Data are analysed in the lepton-plus- jets final state as well as the jets-plus-ETmissE_{\mathrm{T}}^{\mathrm{miss}} final state. The search exploits the events with the high multiplicity of bb-jets, the high scalar sum of transverse momenta of all final state objects, and the presence of boosted hadronically-decaying resonances reconstructed as large-radius jets.
