Up to $79.8$ fb$^{-1}$ of proton-proton collision data collected at $\\sqrt{s}= $ 13 TeV with the ATLAS detector are used. Results are presented for the gluon-gluon fusion and vector-boson fusion processes, and for associated production with vector bosons or top-quarks. The global signal strength is determined to be $\\mu = 1.11^{+0.09}_{-0.08}$. The combined measurement yields an observed (expected) significance for the vector-boson fusion production process of $6.5\\sigma$ ($5.3\\sigma$). Measurements in kinematic regions defined within the simplified template cross section framework are also shown. The results are interpreted in terms of modifiers applied to the Standard Model couplings of the Higgs boson to other particles, and are used to set exclusion limits on parameters in two-Higgs-doublet models and in the simplified Minimal Supersymmetric Standard Model. No significant deviations from Standard Model predictions are observed.','cdsLink':'','journal':'Phys. Rev.

Standard Model processes rarely produce these final states, but there are several models of physics beyond the Standard Model that predict an enhanced rate of production of such events; the ones considered here are production of vector-like quarks, enhanced four-top-quark production, pair production of chiral $b^\\prime$-quarks, and production of two positively charged top quarks. Eleven signal regions are defined; subsets of these regions are combined when searching for each class of models. In the three signal regions primarily sensitive to positively charged top quark pair production, the data yield is consistent with the background expectation. There are more data events than expected from background in the set of eight signal regions defined for searching for vector-like quarks and chiral $b^\\prime$-quarks, but the significance of the discrepancy is less than two standard deviations.

Since W bosons decay to the three lepton generations equally, while $H^+$ may predominantly decay into $\\tau\\nu$, charged Higgs bosons can be searched for using the violation of lepton universality in top quark decays. The analysis in this paper is based on 4.6/fb of proton-proton collision data at $\\sqrt{s}$ = 7 TeV collected by the ATLAS experiment at the Large Hadron Collider. Signatures containing leptons (e or $\\mu$) and/or a hadronically decaying $\\tau (\\tau_{had})$ are used. Event yield ratios between $e+\\tau_{had}$ and $e+\\mu$, as well as between $\\mu+\\tau_{had}$ and $\\mu+e$, final states are measured in the data and compared to predictions from simulations. This ratio-based method reduces the impact of systematic uncertainties in the analysis. No significant deviation from the Standard Model predictions is observed. With the assumption that the branching fraction $B(H^+ \\to \\tau\\nu)$ is 100%, upper limits in the range 3.2%-4.4% can be placed on the branching fraction $B(t \\to bH^+)$ for charged Higgs boson masses $m_{H+}$ in the range 90-140 GeV.

We search for such a resonance using the final state where both $W$ bosons from the top quark decay into either an electron and electron-neutrino or a muon and muon-neutrino (dilepton final state). The data were recorded by the ATLAS experiment during 2011 and correspond to a total integrated luminosity of 1.04/fb. No statistically significant excess above the Standard Model expectation is observed. Upper limits at the 95\\% Confidence Limit (C.L) are set on the cross section times branching ratio of the resonance decaying to $t\\bar{t}$ pairs as a function of the resonance pole mass. A lower mass limit of 0.84~TeV is set for the case of a Kaluza Klein gluon resonance in the Randall-Sundrum Model.','cdsLink':'https://cds.cern.ch/record/1376423','journal':'Preliminary','journalSub':'20-AUG-11','ecm':'7','luminosity':'1 fb-1','keywords':'7 TeV,BSM resonance,Other top properties,Top properties measurements,BSM search,Top pair,2 leptons','links':'@linkBegin@https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/CONFNOTES/ATLAS-CONF-2011-123/@linkEnd@Documents@descriptionEnd@

In the Minimal Supersymmetric Standard Model, for example, the dominant production mode at the LHC for these Higgs bosons, when $m_{H^+} < m_t$, takes place in $t\\overline{t}$ events via the top-quark decay $t\\rightarrow H^{+}b$ with $H^{+}\\rightarrow\\tau \\nu$ dominating for most values of $\\tan\\beta$. Two channels with a hadronically decaying $\\tau$ coming from the charged Higgs boson are studied.

Discriminating variables were identified, which allow the distinction between the leptons produced in $\\tau \\rightarrow l+ \\nu\\mbox{s}$ (arising in decays of $W$ or charged Higgs bosons) and the leptons coming directly from $W$ boson decays. This paper aims at validating these variables, in single-lepton and dilepton $t\\bar{t}$ events, through a comparison between Monte Carlo simulations and 35 pb$^{-1}$ of ATLAS data collected in 7 TeV proton-proton collisions at the LHC, in 2010. We find that Monte Carlo simulations agree well with the ATLAS data. The impact of systematic uncertainties is also discussed.','cdsLink':'https://cds.cern.ch/record/1336747','journal':'Preliminary','journalSub':'10-MAR-11','ecm':'7','luminosity':'35 pb-1','keywords':'7 TeV,Charged Higgs searches,Taus','links':'@linkBegin@https://atlas.web.cern.ch/Atlas/GROUPS/PHYSICS/CONFNOTES/ATLAS-CONF-2011-018@linkEnd@Documents@descriptionEnd@
