Journal ArticleDOI

Search for anomalous production of di-lepton events with missing transverse momentum in e+e- collisions at √S = 161 and 172 GeV

K. Ackerstaff, +356 more
TL;DR: In this paper, events containing two charged leptons and significant missing transverse momentum are selected from a data sample corresponding to a total integrated luminosity of 20.6 pb\(−1) at center-of-mass energies of 161 GeV and 172 GeV.
Journal ArticleDOI

Photonic events with missing energy in e+e- collisions at √s = 189 GeV

Giovanni Abbiendi, +324 more
TL;DR: In this article, the authors derived upper bounds on the number of light neutrino species in the presence of a single photon or with an acoplanar photon pair in the OPAL detector at LEP.
Journal ArticleDOI

Measurement of the production cross section of jets in association with a Z boson in pp collisions at √s = 7 TeV with the ATLAS detector

Georges Aad, +2943 more
TL;DR: In this article, the authors measured the production of jets of particles in association with a Z boson in pp collisions at root s = 7 TeV, using data corresponding to an integrated luminosity of 4.6 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider.
Journal ArticleDOI

Evidence for the associated production of a W boson and a top quark in ATLAS at √s = 7 TeV

Georges Aad, +2856 more
- 17 Sep 2012 - 
TL;DR: In this article, the authors presented evidence for the associated production of a W boson and a top quark using 2.05 fb(-1) of pp collision data at root s = 7 TeV accumulated with the ATLAS detector at the LHC.
Journal ArticleDOI

Search for long-lived stopped R-hadrons decaying out-of-time with pp collisions using the ATLAS detector

Georges Aad, +2917 more
- 03 Dec 2013 - 
TL;DR: In this paper, an updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb(-1) of pp collisions at 7 and 8 TeV, respectively.
