Abstract:
In this talk I will present the work that is the basis of my thesis (which I will defend in October). Charged Higgs bosons are predicted in several beyond the standard models, including supersymmetric models. The ATLAS collaboration has published two searches for a charged Higgs boson decaying to top-bottom pairs using both 8 and 13 TeV data, a third one is in the works.
I will review the methods and results of these searches and discuss my contributions.
The LHC is scheduled for a few upgrades in the coming years, phase 1 after the current physics run finishes next year, and phase 2 in the first half of the 2020's. After the phase 2 upgrade the luminosity is expected to reach 10 times the nominal value, and the experiments have to be upgraded accordingly to handle the high rates. I will describe our work of developing a fast hardware track trigger using pattern matching techniques.
