• #### Search for microscopic black holes and string balls in final states with leptons and jets with the ATLAS detector at √s = 8 TeV ﻿

(Peer reviewed; Journal article, 2014-08-18)
A search for an excess of events with multiple high transverse momentum objects including charged leptons and jets is presented, using 20.3 fb−1 of proton-proton collision data recorded by the ATLAS detector at the Large ...
• #### Search for pair-produced massive coloured scalars in four-jet final states with the ATLAS detector in proton-proton collisions at $\sqrt{s}$ = 7 TeV ﻿

(Peer reviewed; Journal article, 2013-01)
A search for pair-produced massive coloured scalar particles decaying to a four-jet final state is performed by the ATLAS experiment at the LHC in proton-proton collisions at $\sqrt{s}$ = 7 TeV. The analysed data sample ...
• #### Search for quantum black hole production in high-invariant-mass lepton + jet final states using pp collisions at √s = 8 TeV and the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-03-05)
This Letter presents a search for quantum black-hole production using 20.3  fb⎻¹ of data collected with the ATLAS detector in pp collisions at the LHC at √s=8  TeV. The quantum black holes are assumed to decay into a final ...
• #### Search for resonances decaying into top-quark pairs using fully hadronic decays in pp collisions with ATLAS at $\sqrt{s}$ = 7 TeV ﻿

(Peer reviewed; Journal article, 2013-01)
A search for resonances produced in 7 TeV proton-proton collisions and decaying into top-quark pairs is described. In this Letter events where the top-quark decay produces two massive jets with large transverse momenta ...
• #### Study of heavy-flavor quarks produced in association with top-quark pairs at √s =7 TeV using the ATLAS detector ﻿

(Peer reviewed; Journal article, 2014-04-21)
Using a sample of dilepton top-quark pair (tt¯) candidate events, a study is performed of the production of top-quark pairs together with heavy-flavor (HF) quarks, the sum of tt¯+b+X and tt¯+c+X, collectively referred to ...
