Search for a charged Higgs Boson in proton-proton collisions at the LHC using the ATLAS detector
… using data recorded in 2011 and 2012 by the ATLAS detector at the LHC. The $H^{\pm}$ bosons are predicted by some extensions of the Standard Model (SM) that include multiple Higgs doublet fields, such as the Minimal Supersymmetric Standard Model. None of these searches has found evidence for …

Measurement of top-antitop differential cross sections in the di-lepton channel with ATLAS in p-p collisions at 7TeV
… proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider. This data corresponds to an integrated luminosity of \lumitot. Events with top quark pair signatures are selected in the di-lepton channel. The reconstructed differential distributions are subtracted with …

Search for flavor changing neutral currents in top quark decays using a two-leptons+track selection
A search for flavor-changing neutral currents in top quark decays is described. Data collected at a center- of-mass energy of √s = 7 TeV during 2011 corresponding to an integrated luminosity of 2.1 fb^{-1} are used. A cut-based analysis is used on top quark pair production events, where one top …

A search for the ttH (H → bb) channel at the Large Hadron Collider with the ATLAS detector using a matrix element method
… the Large Hadron Collider and collected by the ATLAS detector, this analysis utilizes multiple advanced techniques to search for tt ̄H signatures with a 125 GeV Higgs boson decaying to two b-quarks. After categorizing selected events based on their jet and b-tag multiplicities, signal rich …
