Measurement of inclusive jet charged-particle fragmentation functions in Pb+Pb collisions at √sNN = 2.76 TeV with the ATLAS detector

Georges Aad, +3036 more
- 11 Jun 2014 - 
TL;DR: In this article, the authors measured the charged-particle fragmentation functions of jets produced in ultra-relativistic nuclear collisions to provide insight into the modification of parton showers in the hot, dense medi...
Journal ArticleDOI

Measurement of hard double-parton interactions in W(-> lv) plus 2-jet events at root s=7 TeV with the ATLAS detector

Georges Aad, +2962 more
TL;DR: In this paper, the production of W bosons in association with two jets in proton-proton collisions at a center-of-mass energy of root s = 7 TeV has been analyzed for the presence of double-parton interactions using data corresponding to an integrated luminosity of 36 pb(-1), collected with the ATLAS detector at the Large Hadron Collider.
Journal ArticleDOI

Searches for Extended and Point-like Neutrino Sources with Four Years of IceCube Data

M. G. Aartsen, +301 more
TL;DR: In this article, the authors present results on searches for point-like sources of neutrinos using four years of IceCube data, including the first year of data from the completed 86-string detector.

Technical Design Report for the Phase-I Upgrade of the ATLAS TDAQ System

Georges Aad, +2876 more
TL;DR: The Phase-I upgrade of the ATLAS Trigger and Data Acquisition (TDAQ) system is proposed in this article, which can efficiently trigger and record data at instantaneous luminosities that are up to three times that of the original LHC design while maintaining trigger thresholds close to those used in the initial run of the LHC.
Journal ArticleDOI

Search for Prompt Neutrino Emission from Gamma-Ray Bursts with IceCube

M. G. Aartsen, +300 more
TL;DR: In this article, the authors present constraints derived from a search of four years of IceCube data for a prompt neutrino flux from gamma-ray bursts (GRBs) that disfavor much of the parameter space for the latest models.
