Search for Heavy Long-Lived Multi-Charged Particles in pp Collisions at √s̅ = 8 TeV Using the ATLAS Detector
(Springer New York Llc, 2015-08-08)
A search for heavy long-lived multi-charged particles is performed using the ATLAS detector at the LHC. Data collected in 2012 at √s = 8 TeV from pp collisions corresponding to an integrated luminosity of 20.3 fb⁻¹ are ...
Search for an Additional, Heavy Higgs Boson in the H → ZZ Decay Channel at √s̅ = 8 TeV in pp Collision Data with the ATLAS Detector
(Springer, 2016-01)
A search is presented for a high-mass Higgs boson in the H → ZZ → ℓ+ℓ−ℓ+ℓ−, H → ZZ → ℓ+ℓ−νν̅ , H → ZZ → ℓ+ℓ−qq̅, and H → ZZ → νν̅qq̅ decay modes using the ATLAS detector at the CERN Large Hadron Collider. The search uses ...
Measurement of Higgs Boson Production in the Diphoton Decay Channel in pp Collisions at Center-Of-Mass Energies of 7 and 8 TeV with the ATLAS Detector
(American Physical Society, 2014-12-24)
A measurement of the production processes of the recently discovered Higgs boson is performed in the two-photon final state using 4.5 fb⁻¹ of proton-proton collisions data at √s = 7 TeV and 20.3 fb⁻¹ at √s = 8 TeV collected ...
Searches for Scalar Leptoquarks in pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer New York LLC, 2016-01-05)
Searches for pair-produced scalar leptoquarks are performed using 20 fb⁻¹ of proton–proton collision data provided by the LHC and recorded by the ATLAS detector at √s̅ = 8 TeV. Events with two electrons (muons) and two or ...
Measurement of the Production and Lepton Charge Asymmetry of W Bosons in Pb+Pb Collisions at √{S_{NN}} = 2.76 TeV with the ATLAS Detector
(Springer New York LLC, 2015-01-22)
A measurement of boson production in lead-lead collisions at √{S_{NN}} = 2.76 TeV is presented. It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated ...
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
(Springer, 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 High-Mass Dilepton Resonances in pp Collisions at √s = 8 TeV with the ATLAS Detector
(American Physical Society, 2014-09-19)
The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying to dielectron or dimuon final states. Results are presented from an analysis of proton-proton (pp) collisions at a ...
Search for New Phenomena in Events Containing a Same-Flavour Opposite-Sign Dilepton Pair, Jets, and Large Missing Transverse Momentum in √s̅ =13 TeV pp Collisions with the ATLAS Detector
(2018-05-15)
To probe the W tb vertex structure, top-quark and W-boson polarisation observables are measured from t-channel single-top-quark events produced in proton-proton collisions at a centre-of-mass energy of 8 TeV. The dataset ...
Evidence of Wγγ Production in pp Collisions at √s̅ = 8 TeV and Limits on Anomalous Quartic Gauge Couplings with the ATLAS Detector
(American Physical Society, 2015-07-16)
This Letter reports evidence of triple gauge boson production pp → W(ℓν)γγ + X, which is accessible for the first time with the 8 TeV LHC data set. The fiducial cross section for this process is measured in a data sample ...
