• #### Search for long-lived neutral particles decaying into lepton jets in proton-proton collisions at √s= 8TeV with the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-11)
Several models of physics beyond the Standard Model predict neutral particles that decay into final states consisting of collimated jets of light leptons and hadrons (so-called “lepton jets”). These particles can also be ...
• #### Search for neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at √s= TeV with the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-11-12)
A search for the neutral Higgs bosons predicted by the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is performed on data from proton-proton collisions at a centre-of-mass energy of 8TeV collected ...
• #### Search for new resonances in $W\gamma$ and $Z\gamma$ Final States in $pp$ Collisions at $\sqrt{s}=8\,\mathrm{TeV}$ with the ATLAS Detector ﻿

(Peer reviewed; Journal article, 2014-11-10)
This letter presents a search for new resonances decaying to final states with a vector boson produced in association with a high transverse momentum photon, $V\gamma$, with $V= W(\rightarrow \ell \nu)$ or $Z(\rightarrow ... • #### Search for non-pointing and delayed photons in the diphoton and missing transverse momentum final state in 8 TeV \(pp$ collisions at the LHC using the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-12-10)
A search has been performed, using the full 20.3 fb$^{-1}$ data sample of 8 TeV proton--proton collisions collected in 2012 with the ATLAS detector at the LHC, for photons originating from a displaced vertex due to the ...
• #### Search for pair and single production of new heavy quarks that decay to a Z boson and a third-generation quark in pp collisions at √s=8 TeV with the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-11-19)
A search is presented for the production of new heavy quarks that decay to a Z boson and a third-generation Standard Model quark. In the case of a new charge +2/3 quark (T ), the decay targeted is T → Zt, while the decay ...
• #### Search for scalar diphoton resonances in the mass range 65-600 GeV with the ATLAS detector in pp collision data at √s = 8  TeV ﻿

(Peer reviewed; Journal article, 2014-10-20)
A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using 20.3  fb⎻¹ of s√=8  TeV pp collision data collected with the ATLAS detector at the Large Hadron ...
• #### Search for squarks and gluinos with the ATLAS detector in final states with jets and missing transverse momentum using √s=8 TeV proton-proton collision data ﻿

(Peer reviewed; Journal article, 2014-09)
A search for squarks and gluinos in final states containing high-pT jets, missing transverse momentum and no electrons or muons is presented. The data were recorded in 2012 by the ATLAS experiment in √s = 8TeV proton-proton ...
• #### Search for the lepton flavor violating decay Z →eμ in pp collisions at √s=8TeV with the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-10-23)
The ATLAS detector at the Large Hadron Collider is used to search for the lepton flavor violating process Z→eμ in pp collisions using 20.3  fb⎻¹ of data collected at √s=8  TeV. An enhancement in the eμ invariant mass ...
• #### Search for top squark pair production in final states with one isolated lepton, jets, and missing transverse momentum in √s = 8 TeV pp collisions with the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-11)
The results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported. The analysis is performed with proton-proton collision data at s√ ...
