Developments in the search for a heavy charged Higgs boson — •Francesco Peri, Heiko Lacker, and Janet Dietrich — HU-Berlin

Many Beyond-the-Standard Model (BSM) scenarios predict charged Higgs bosons (H^±). In particular, an additional Higgs doublet naturally appears in the Minimal Supersymmetric Standard Model (MSSM). The production mechanisms and decays of such particles strongly depend on their mass. This presentation focuses on heavy charged Higgs bosons, with a mass larger than the top-quark mass, whose predicted production cross section at the Large Hadron Collider is not negligible. In this case, the dominant production mode is in association with a top quark, while the decay is into a top-bottom pair. In this talk, the current status of a search for tbH^± production with the ATLAS experiment is presented. The latest public results are summarised, showing upper limits on the production cross section times the decay branching fraction, and proposing possible improvements.
