Measurement of the top quark mass in the tt → lepton+jets and tt → dilepton channels using √s = 7 TeV ATLAS data
(2015)
The top quark mass was measured in the channels tt → lepton+jets and tt → dilepton (lepton = e, μ) based on ATLAS data recorded in 2011. The data were taken at the LHC with a proton–proton centre-of-mass energy of √s = 7 ...
Search for invisible decays of the Higgs boson produced in association with a hadronically decaying vector boson pp collisions at √s = 8 TeV with the ATLAS detector
(2015)
A search for Higgs boson decays to invisible particles is performed using 20.3 fb–1 of pp collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the Large Hadron Collider. The process considered ...
Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √s = 8 TeV with the ATLAS detector
(2015)
Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √s = 8 TeV data collected in 2012 with the ATLAS detector at the ...
Evidence of Wγγ production in pp collisions at √s=8 TeV and limits on anomalous quartic gauge couplings with the ATLAS detector
(2015)
This Letter reports evidence of triple gauge boson production pp → W(ℓ ν)γγ+X, which is accessible for the first time with the 8TeV LHC data set. The fiducial cross section for this process is measured in a data sample ...
