Measurement of the production cross-section of ψ(2S) →J/ψ (→ μ + μ¯)π + π¯ in pp collisions at √s = 7 TeV at ATLAS

Georges Aad, +2911 more
- 12 Sep 2014 - 
TL;DR: In this article, the prompt and non-prompt production crosssections for psi(2S) mesons are measured using 2.1 fb(-1) of pp collision data at a centre-of-mass energy of 7TeV recorded by the ATLAS experiment at the LHC.
Journal ArticleDOI

Time-dependent angular analysis of the decay B-s(0) -> J/psi phi and extraction of Delta Gamma(s) and the CP-violating weak phase phi(s) by ATLAS

Georges Aad, +2924 more
- 01 Dec 2012 - 
TL;DR: In this article, the CP-violating weak phase phi(s) and the decay width difference were measured using 4.9 fb(-1) of integrated luminosity collected in 2011 by the ATLAS detector from LHC pp collisions at a centre-of-mass energy root s = 7 TeV.
Journal ArticleDOI

First search for extremely high energy cosmogenic neutrinos with the IceCube Neutrino Observatory

Rasha Abbasi, +261 more
- 07 Oct 2010 - 
TL;DR: The results of the search for extremely high energy neutrinos with energies above 10(7) GeV obtained with the partially constructed IceCube in 2007 were reported in this paper.
Journal ArticleDOI

Evidence for chain-like production of strange baryon pairs in jets

P. D. Acton, +586 more
- 20 May 1993 - 
TL;DR: In this paper, the production dynamics of baryon-antibaryon pairs are investigated using hadronic Z0 decays, recorded with the OPAL detector, which contain at least two identified baryons.
Journal ArticleDOI

Measurement of colour flow with the jet pull angle in tt¯ events using the ATLAS detector at s√=8 TeV

Georges Aad, +2892 more
- 12 Nov 2015 - 
TL;DR: In this paper, the pull angle is measured for jets produced in t (t) over bar events with one W boson decaying leptonically and the other decaying to jets using 20.3 fb(-1) of data recorded with the ATLAS detector at a center-of-mass energy of root s = 8 TeV at the LHC.
