X → t ¯ X → VV hadronic X → VV semi-leptonic X → VV leptonic X → γγ/γ Z / γ W t X → hh (125 GeV) Aka searches for heavy resonances in di-boson and t ¯ t final states free from extended Higgs sector interpretation, from 2014 ◮ What are we talking about?! ◮ One additional spin-0 EW singlet (Dark portal, ... see S. Dawson talk) ◮ Extra dimensions / Strong-like theories (spin-0/2 resonances) ∗ ◮ Extended gauge sector (spin-1 resonances) ∗ ∗ Asking for poetic licence with respect to the original talk title ◮ Why this is a separated talk? ◮ Extended mass range hypothesis no naturality arguments limiting expectations up to TeV range Boosted searches included ◮ The large natural with of 2HDM or MSSM Higgs bosons is not considered results usually derived negligible width approximation (Γ X / M X ≪≪≪ 0 . 1) Alexandra Oliveira ATLAS + CMS Other heavy ”Higgs” bosons 2 / 19

X → t ¯ X → VV hadronic X → VV semi-leptonic X → VV leptonic X → γγ/γ Z / γ W t X → hh (125 GeV) Final states mentioned in this talk ◮ X → VV hadronic ◮ X → VV semi-leptonic ◮ X → VV leptonic ◮ X → γγ/γ Z / γ W ◮ X → t ¯ t ◮ X → hh (the 125 GeV one) - signal extraction method - object reconstruction techniques - model dependencies Model You are invited to go to the references (and backup) for sensitivity results and other many interesting details. (There is no excess bigger than 2 σ in the analyses mentioned in this talk) Alexandra Oliveira ATLAS + CMS Other heavy ”Higgs” bosons 3 / 19
