Evidence for Single Top-Quark Production in the S-Channel in Proton-Proton Collisions at √s̅ = 8 TeV with the ATLAS Detector Using the Matrix Element Method
(Elsevier Science Bv, 2016-03-08)
This Letter presents evidence for single top-quark production in the s-channel using proton-proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector at the CERN Large Hadron Collider. The analysis is ...
Search for New Phenomena with Large Jet Multiplicities and Missing Transverse Momentum Using Large-Radius Jets and Flavour-Tagging at ATLAS in 13 TeV pp Collisions
(Springer, 2018-09-27)
A search is presented for particles that decay producing a large jet multiplicity and invisible particles. The event selection applies a veto on the presence of isolated electrons or muons and additional requirements on ...
Measurement of the Cross Section of High Transverse Momentum Z → bb̅ Production in Proton-Proton Collisions at √s = 8 TeV with the ATLAS Detector
(Elsevier, 2014-09-16)
This Letter reports the observation of a high transverse momentum Z → bb̅ signal in proton-proton collisions at √s = 8 TeV and the measurement of its production cross section. The data analysed were collected in 2012 with ...
Search for Higgs Boson Pair Production in the bb̅bb̅ Final State from pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer, 2015-09-09)
A search for Higgs boson pair production pp → hh is performed with 19.5 fb⁻¹ of proton-proton collision data at √s̅ = 8 TeV, which were recorded by the ATLAS detector at the Large Hadron Collider in 2012. The decay products ...
Measurements of Jet Vetoes and Azimuthal Decorrelations in Dijet Events Produced in PP Collisions at √s = 7 TeV Using the ATLAS Detector
(Springer, 2014-10-31)
Additional jet activity in dijet events is measured using pp collisions at ATLAS at a centre-of-mass energy of 7 TeV, for jets reconstructed using the anti-k(t) algorithm with radius parameter R = 0.6. This is done using ...
Search for Flavour-Changing Neutral Current Top Quark Decays t → Hq In pp Collisions at √s̅ = 8 TeV with the ATLAS Detector
(Springer, 2015-12-10)
A search for flavour-changing neutral current decays of a top quark to an up-type quark (q = u; c) and the Standard Model Higgs boson, where the Higgs boson decays to b (b) over bar, is presented. The analysis searches for ...
Search for Super Symmetry in Events with B-Tagged Jets and Missing Transverse Momentum in pp Collisions at √s=13 TeV with the ATLAS Detector
(Springer, 2018-09-27)
A search for the supersymmetric partners of the Standard Model bottom and top quarks is presented. The search uses 36.1 fb⁻¹ of pp collision data at √s = 13 TeV collected by the ATLAS experiment at the Large Hadron Collider. ...
Search for Squarks and Gluinos in Events with an Isolated Lepton, Jets, and Missing Transverse Momentum at √s=13 TeV with the ATLAS Detector
(Amer Physical Soc, 2018-09-27)
The results of a search for squarks and gluinos in final states with an isolated electron or muon, multiple jets and large missing transverse momentum using proton-proton collision data at a center-of-mass energy of √s = ...
Measurements of Top-Quark Pair to Z-Boson Cross-Section Ratios at √s̅ = 13 , 8, 7 TeV with the ATLAS Detector
(Springer Verlag, 2018-09-12)
Ratios of top-quark pair to Z-boson cross sections measured from proton-proton collisions at the LHC centre-of-mass energies of √s̅ = 13 TeV, 8 TeV, and 7 TeV are presented by the ATLAS Collaboration. Single ratios, at a ...
