Search for dark mesons decaying to top and bottom quarks in proton-proton collisions at SQUARE ROOTs = 13 TeV with the ATLAS detector

Popis výsledku v původním jazyce

A search for dark mesons originating from strongly-coupled, SU(2) dark flavorsymmetry conserving models and decaying gaugephobically to pure Standard Model finalstates containing top and bottom quarks is presented. The search targets fully hadronic finalstates and final states with exactly one electron or muon and multiple jets. The analyzeddata sample corresponds to an integrated luminosity of 140 fb-1 of proton-proton collisionscollected at SQUARE ROOTs = 13TeV with the ATLAS detector at the Large Hadron Collider. Nosignificant excess over the Standard Model background expectation is observed and theresults are used to set the first direct constraints on this type of model. The two-dimensionalsignal space of dark pion masses mπD and dark rho-meson masses mρD is scanned. FormπD/mρD = 0.45, dark pions with masses mπD &lt; 940 GeV are excluded at the 95% CL, whilefor mπD/mρD = 0.25 masses mπD &lt; 740 GeV are excluded.
