 Beyond standard model searches on diboson resonances, vector-like quarks, and heavy bosons with top in the final state / Pazzini, Jacopo (INFN, Padua ; Padua U.) /ATLAS and CMS Collaborations The most recent results in the searches for physics beyond the standard model at the ATLAS and CMS experiments are presented, based on the data collected in proton-proton collisions at the CERN LHC at the center-of-mass energy of $\sqrt{s}=13$~TeV, with emphasis on the production of vector-like quarks and the production of heavy new resonance decaying to third generation SM quarks or gauge bosons.The decay of these new heavy states will present the striking feature of generating highly collimated decay products, as the results of a large Lorentz boost.For this reasons, the reconstruction and identification of hadronic decays are critical to most searches and are described in detail in this contribution..

 Measurements of inclusive and differential fiducial cross-sections of $t\bar{t}\gamma$ production in leptonic final states at $\sqrt{s} = 13$ TeV in ATLAS / ATLAS Collaboration Inclusive and differential cross-sections for the production of a top-quark pair in association with a photon are measured with proton-proton collision data corresponding to an integrated luminosity of 36.1 fb$^{-1}$, collected by the ATLAS detector at the LHC in 2015 and 2016 at a centre-of-mass energy of 13 TeV.

 Searches for Higgs bosons with dark matter at the Large Hadron Collider / Gallinaro, Michele (LIP, Lisbon) /ATLAS and CMS Collaborations Convincing and direct evidence for dark matter (DM) on galactic scales comes from the observation of the rotation curves of galaxies. At particle colliders, searches for DM involve the production of a pair of stable electrically neutral and weakly interacting particles with a signature of missing transverse energy ($E^{\rm T}_{\rm miss}$) recoiling against a SM particle.
