Study of the material of the ATLAS inner detector for Run 2 of the LHC
(IOP Publishing, 2017-07)
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 ...
Search for a light charged Higgs boson in the decay channel H+->csbar in ttbar events using pp collisions at sqrt(s) = 7 TeV with the ATLAS detector
(Springer, 2013-06-06)
A search for a charged Higgs boson (H+) in ttbar decays is presented, where one of the top quarks decays via t->H+b, followed by H+->two jets (csbar). The other top quark decays to Wb, where the W boson then decays into a ...
Measurement of the Azimuthal Angle Dependence of Inclusive Jet Yields in Pb+Pb Collisions at √sNN= 2.76 TeV with the ATLAS detector
(Amer Physical Soc, 2013-06-27)
Measurements of the variation of inclusive jet suppression as a function of relative azimuthal angle, Delta phi, with respect to the elliptic event plane provide insight into the path-length dependence of jet quenching. ...
Search for a new resonance decaying to a W or Z boson and a Higgs boson in the /ν/νν + bb¯ final states with the ATLAS detector
(Springer, 2015-05)
A search for a new resonance decaying to a W or Z boson and a Higgs boson in the ℓℓ/ℓν/νν+bb¯ final states is performed using 20.3 fb−1 of pp collision data recorded at s√= 8 TeV with the ATLAS detector at the Large Hadron ...
Search for direct pair production of a chargino and a neutralino decaying to the 125 GeV Higgs boson in √s = 8 TeV pp collisions with the ATLAS detector
(Springer, 2015-05)
A search is presented for the direct pair production of a chargino and a neutralino pp→χ~±1χ~02 , where the chargino decays to the lightest neutralino and the W boson, χ~±1→χ~01(W±→ℓ±ν) , while the neutralino decays to the ...
Measurement of colour flow with the jet pull angle in tt¯ events using the ATLAS detector at s√=8 TeV
(Elsevier Science, 2015-09)
The distribution and orientation of energy inside jets is predicted to be an experimental handle on colour connections between the hard–scatter quarks and gluons initiating the jets. This Letter presents a measurement of ...
Measurements of the Total and Differential Higgs Boson Production Cross Sections Combining the H-> gg and H->ZZ* -> 4l Decay Channels at sqrt(s)=8TeV with the ATLAS Detector
(American Physical Society, 2015-04)
Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3 fb-1 of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of s=8 TeV and recorded ...
Observation of top-quark pair production in association with a photon and measurement of the t¯tγ production cross section in pp collisions at sqrt(s) = 7 TeV using the ATLAS detector
(American Physical Society, 2015-04)
A search is performed for top-quark pairs (tt¯) produced together with a photon (γ) with transverse energy greater than 20 GeV using a sample of tt¯ candidate events in final states with jets, missing transverse momentum, ...
Search for lepton-flavour-violating H → μτ decays of the Higgs boson with the ATLAS detector
(Springer, 2015-11)
A direct search for lepton–flavour–violating (LFV) H → µτ decays of the recently discovered Higgs boson with the ATLAS detector at the LHC is presented. The analysis is performed in the H → µτhad channel, where τhad is a ...
