Description
Composite Higgs Models predict quark partners at the TeV scale which can be produced at the LHC Run II. The decay of such heavy quark partners lead to highly boosted objects in the final state (e.g. tops, Higgses and electroweak gauge bosons) which require refined search strategies. In this talk we propose boosted object searches which utilizes a simplified b-tagging procedure and the Template Overlap Method to tag the massive boosted objects and reject the corresponding backgrounds. In addition, we propose a new, pileup insensitive method, to tag forward jets which characterize our signal events. We show that this search strategy offers a new window to both detecting and measuring quark partners of mass up to ~ 2 TeV.
