Measurement of distributions sensitive to the underlying event in inclusive Z-boson production in pp collisions at √s = 7 TeV with the ATLAS detector

Georges Aad, +2875 more
- 10 Dec 2014 - 
TL;DR: In this article, a measurement of charged particle distributions sensitive to the properties of the underlying event is presented for an inclusive sample of events containing a Z-boson, decaying to an electron or muon pair.
Journal ArticleDOI

Search for a standard model Higgs boson in the H→ZZ→ℓ(+)ℓ(-)νν decay channel with the ATLAS detector.

Georges Aad, +3107 more
- 22 Nov 2011 - 
TL;DR: In this article, a search for a heavy standard model Higgs boson decaying via H -> ZZ -> l(+)l(-)v (v) over bar, where l = e, mu, is presented.
Journal ArticleDOI

Search for third generation scalar leptoquarks in pp collisions at s√=7 TeV with the ATLAS detector

Georges Aad, +2935 more
- 10 Jun 2013 - 
TL;DR: In this article, a search for pair-produced third generation scalar leptoquarks is presented, using proton-proton collisions at root s = 7 TeV at the LHC.
Journal ArticleDOI

Search for Pair Production of a New b ′ Quark that Decays into a Z Boson and a Bottom Quark with the ATLAS Detector

Georges Aad, +3071 more
- 16 Aug 2012 - 
TL;DR: A search is reported for the pair production of a new quark b' with at least one b' decaying to a Z boson and a bottom quark, resulting in the exclusion at a 95% confidence level of b' quarks with masses m (b') < 400 GeV that decay entirely via b' → Z+b.
Journal ArticleDOI

Search for Supersymmetry in Events with Large Missing Transverse Momentum, Jets, and at Least One Tau Lepton in 7 TeV Proton-Proton Collision Data with the ATLAS Detector

Georges Aad, +2901 more
- 20 Nov 2012 - 
TL;DR: In this article, a search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying tau lepton, with zero or one additional light lepton (e/mu), has been performed using 4.7 fb(-1) of proton-proton collision data at root s = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider.
