Search for pair production of heavy top-like quarks decaying to a high-pT W boson and a b quark in the lepton plus jets final state at √s=7 TeV with the ATLAS detector
(2013)
A search is presented for production of a heavy up-type quark (t′) together with its antiparticle, assuming a significant branching ratio for subsequent decay into a W boson and a b quark. The search is based on 4.7 fb−1 ...
Search for direct slepton and gaugino production in final states with two leptons and missing transverse momentum with the ATLAS detector in pp collisions at s=7 TeV
(2013)
A search for the electroweak pair production of charged sleptons and weak gauginos decaying into final states with two leptons is performed using 4.7 fb-1 of proton-proton collision data at s=7 TeV recorded with the ATLAS ...
Search for dark matter in events with heavy quarks and missing transverse momentum in pp collisions with the ATLAS detector
(2015-02-24)
Abstract
This article reports on a search for dark matter pair production in association with bottom or top quarks in 20.3 fb−1 of pp collisions collected at √s = 8 TeV by the ATLAS detector at the LHC. Events with large ...
Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s=7 TeV pp collisions with the ATLAS detector
(2013)
A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of s=7 TeV proton–proton collision ...
Search for pair-produced massive coloured scalars in four-jet final states with the ATLAS detector in proton–proton collisions at √s =7 TeV
(2013)
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 √s = 7 TeV. The analysed data sample corresponds ...
Measurements of top quark pair relative differential cross-sections with ATLAS in pp collisions at √s = 7 TeV
(2013)
Measurements are presented of differential crosssections for top quark pair production in pp collisions at
√s = 7 TeV relative to the total inclusive top quark pair production cross-section. A data sample of 2.05 fb−1 ...
Measurement of the top quark mass in the tt¯→dilepton channel from √s=8 TeV ATLAS data
(2016)
The top quark mass is measured in the tt¯→dilepton channel (lepton=e,μ) using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of s=8 TeV and correspond to an ...
Search for new resonances in Wγ and Zγ final states in pp collisions at √s=8 TeV with the ATLAS detector
(Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 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, Vγ with V=W(→ℓν) or Z(→ℓ+ℓ−), where ℓ=e or μ. The measurements ...
