**Search for Charged Higgs using Boosted Top Tagging** — Elin Bergeaas Kuutmann, •Geoffrey Herbert, Heiko Lacker, and Martin zur Nedden — Humboldt Universität zu Berlin

Charged Higgs bosons (*H*^{±}) are predicted by several BSM theories including the Two Higgs Doublet model. The inclusion of an extra Higgs doublet is a simple extension to the standard model and occurs naturally in Supersymmetry.
Current search limits for *H*^{±} are heavily dependent upon chosen values of tan(β), although they currently favour increasingly *H*^{±} heavy masses. Charged Higgs bosons with masses much greater than that of the top quark could be produced with noticeable cross sections at the LHC. Their large masses allow for preferential decay to Top and Bottom quarks which may become boosted with increasing parent particle mass. Boosted Top Tagging techniques could be useful in searching for *H*^{±}, however such particles have a very busy production and decay topology (multiple Top and Bottom quarks). Complex search environments are a new challenge for Boosted Top Tagging techniques and new methods of object reconstruction need to be explored to optimise search strategies.
In this talk, an analysis strategy using HEPTopTagger is presented.
