Search for the 125 GeV Higgs boson in ttH production with ATLAS

The search for the production of the Higgs Boson with a pair of top-anti-top quarks is both very important and very challenging. The final results from run-1 are presented, with about 20 fb^(-1) of data at 8 TeV, as well as first run-2 results with 3.2 fb^(-1) of data at 13 TeV

Search for High-Mass Resonances Decaying to τν\tau\nu in pp Collisions at s\sqrt{s}=13 TeV with the ATLAS Detector

A search for high-mass resonances decaying to τν using proton-proton collisions at s=13  TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. The data were recorded with the ATLAS detector and correspond to an integrated luminosity of 36.1  fb-1. No statistically significant excess above the standard model expectation is observed; model-independent upper limits are set on the visible τν production cross section. Heavy W′ bosons with masses less than 3.7 TeV in the sequential standard model and masses less than 2.2–3.8 TeV depending on the coupling in the nonuniversal G(221) model are excluded at the 95% credibility level.Peer Reviewe
