Analysis of the Wtb vertex from the measurement of triple-differential angular decay rates of single top quarks produced in the t-channel at s√ = 8 TeV with the ATLAS detector
The electroweak production and subsequent decay of single top quarks in the t-channel is determined by the properties of the Wtb vertex, which can be described by the complex parameters of an effective Lagrangian. An ...
Search for top squarks in final states with one isolated lepton, jets, and missing transverse momentum ins=13 TeVppcollisions with the ATLAS detector
(American Physical Society (APS), 2016)
The results of a search for the stop, the supersymmetric partner of the top quark, in final states with one isolated electron or muon, jets, and missing transverse momentum are reported. The search uses the 2015 LHC pp ...
Measurement of detector-corrected observables sensitive to the anomalous production of events with jets and large missing transverse momentum in pp collisions at s√=13 TeV using the ATLAS detector
Observables sensitive to the anomalous production of events containing hadronic jets and missing momentum in the plane transverse to the proton beams at the Large Hadron Collider are presented. The observables are defined ...
Search for supersymmetry in final states with two same-sign or three leptons and jets using 36 fb−1 of s√=13 TeV pp collision data with the ATLAS detector
A search for strongly produced supersymmetric particles using signatures involving multiple energetic jets and either two isolated same-sign leptons (e or μ), or at least three isolated leptons, is presented. The analysis ...
Determination of the strong coupling constant αs from transverse energy-energy correlations in multijet events at s√=8 TeV using the ATLAS detector
Measurements of transverse energy-energy correlations and their associated asymmetries in multi-jet events using the ATLAS detector at the LHC are presented. The data used correspond to s√=8 TeV proton-proton collisions ...
Search for lepton-flavour-violating decays of the Higgs and Z bosons with the ATLAS detector
(Springer Nature, 2017)
Direct searches for lepton flavour violation in decays of the Higgs and Z bosons with the ATLAS detector at the LHC are presented. The following three decays are considered: H → eτ, H → µτ, and Z → µτ. The searches are ...
Search for Dark Matter Produced in Association with a Higgs Boson Decaying to bb¯ using 36 fb−1 of pp collisions at s√=13 TeV with the ATLAS Detector
Several extensions of the Standard Model predict associated production of dark-matter particles with a Higgs boson. Such processes are searched for in final states with missing transverse momentum and a Higgs boson decaying ...
Measurement of long-range multi-particle azimuthal correlations with the subevent cumulant method in pp and p+Pb collisions with the ATLAS detector at the LHC
A detailed study of multi-particle azimuthal correlations is presented using pp data at √s = 5.02 and 13 TeV, and p+Pb data at √sNN = 5.02 TeV, recorded with the ATLAS detector at the LHC. The azimuthal correlations are ...
Study of the material of the ATLAS inner detector for Run 2 of the LHC
The ATLAS inner detector comprises three different sub-detectors: the pixel detector, the silicon strip tracker, and the transition-radiation drift-tube tracker. The Insertable B-Layer, a new innermost pixel layer, was ...
