##### Abstract [en]

Results from searches for charged Higgs bosons in ATLAS and CMS are presented. The searches cover singly charged Higgs boson decays in the $H^+ \rightarrow \tau\nu$, $H^+ \rightarrow t\bar{b}$, $H^+ \rightarrow c\bar{s}$, and $H^+ \rightarrow W^+Z$ modes, and doubly charged Higgs boson decays in the $\Phi^{++}\Phi^{--} \rightarrow 4l$ and $\Phi^{++}\Phi^{-} \rightarrow 3l$ modes, with \SI{7}{TeV} and \SI{8}{TeV} data from the Run 1 of the LHC. The first search for charged Higgs bosons with \SI{13}{TeV} data in the $H^{+} \rightarrow \tau\nu$ decay mode with ATLAS is also presented. The results are interpreted in various theoretical models.

Results from searches for charged Higgs bosons in ATLAS and CMS are presented. The searches cover singly charged Higgs boson decays in the H+→τνH+→τν, H+→tb¯H+→tb¯, H+→cs¯H+→cs¯, and H+→W+ZH+→W+Z modes, and doubly charged Higgs boson decays in the Φ++Φ−−→4lΦ++Φ−−→4l and Φ++Φ−→3lΦ++Φ−→3l modes, with 7 TeV and 8 TeV data from the Run 1 of the LHC. The first search for charged Higgs bosons with 13 TeV data in the H+→τνH+→τν decay mode with ATLAS is also presented. The results are interpreted in various theoretical models.

##### Abstract [en]

This thesis describes a measurement of the Standard Model Higgs boson coupling to fermions in decays to two τ-leptons, a search for charged Higgs bosons in decays to a τ-lepton and a neutrino, as well as the reconstruction, identiﬁcation and triggering of hadronically decaying τ-leptons. The data considered are collected by the ATLAS experiment at the Large Hadron Collider.

The reconstruction and identiﬁcation of hadronically decaying τ-leptons in the ATLAS experiment during Run 2 of the Large Hadron Collider are described, and the performance of the τ trigger is measured in events with top–antitop-quark pairs using data from 13 TeV proton–proton collisions, corresponding to an integrated luminosity of 3.2 fb-1, collected in 2015, and 11.5 fb-1, collected in 2016.

Hadronically decaying τ-leptons are of importance to many physical processes involving Higgs bosons. The coupling of the Standard Model Higgs boson to fermions is measured in decays to two τ-leptons using 7 TeV data corresponding to an integrated luminosity of 4.5 fb-1, collected in 2011, and 8 TeV data corresponding to an integrated luminosity of 20.3 fb-1, collected in 2012. The signal strength is measured to be μ = 1.4, corresponding to an excess over the background-only model of 4.5σ.

Charged Higgs bosons are searched for in decays to a τ-lepton and a neutrino, where the τ-lepton decays hadronically. 13 TeV data corresponding to an integrated luminosity of 14.7 fb-1, collected in 2015 and 2016, are used. No excess over the Standard Model background is observed, and the 95 % conﬁdence-level exclusion limits on σ(pp → [b]tH+) × (H+ → τν) are set to 2.0 pb–8 fb in the range 200–2000 GeV.
