Limits on the production of the standard model Higgs boson in pp collisions at s=7 TeV with the ATLAS detector
(Peer reviewed; Journal article, 2011-09-20)A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb−1 collected by the ATLAS detector ... -
Luminosity determination in pp collisions at s=7 TeV using the ATLAS detector at the LHC
(Peer reviewed; Journal article, 2011-04-27)Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at s=7 TeV are presented. The luminosity is independently determined using several detectors and multiple ... -
Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector
(Peer reviewed; Journal article, 2011-02-03)Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb−1 recorded at the ... -
Measurements of underlying-event properties using neutral and charged particles in pp collisions at √ s = 900 GeV and √ s = 7 TeV with the ATLAS detector at the LHC
(Peer reviewed; Journal article, 2011-05-10)We present first measurements of charged and neutral particle-flow correlations in pp collisions using the ATLAS calorimeters. Data were collected in 2009 and 2010 at centre-of-mass energies of 900 GeV and 7 TeV. Events ... -
Production of pions, kaons and protons in pp collisions at s=900 GeV with ALICE at the LHC
(Peer reviewed; Journal article, 2011-06-15)The production of π +, π −, K+, K−, p, and p at mid-rapidity has been measured in proton-proton collisions at s=900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the ... -
Search for single top quark production via contact interactions at LEP2
(Peer reviewed; Journal article, 2011-02-15)Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI detector at LEP2. The data were accumulated at centre-ofmass ... -
Strange particle production in proton–proton collisions at s=09 with ALICE at the LHC The ALICE Collaboration
(Peer reviewed; Journal article, 2011-03-30)The production of mesons containing strange quarks (, φ) and both singly and doubly strange baryons (, , and ) are measured at mid-rapidity in pp collisions at s = 0.9 TeV with the ALICE experiment at the LHC. The results ... -
Studies of the performance of the ATLAS detector using cosmic-ray muons
(Peer reviewed; Journal article, 2011-03-29)Muons from cosmic-ray interactions in the atmosphere provide a high-statistics source of particles that can be used to study the performance and calibration of the ATLAS detector. Cosmic-ray muons can penetrate to the ... -
A study of the b-quark fragmentation function with the DELPHI detector at LEP I and an averaged distribution obtained at the Z Pole
(Peer reviewed; Journal article, 2011-02-23)The nature of b-quark jet hadronisation has been investigated using data taken at the Z peak by the DELPHI detector at LEP. Two complementarymethods are used to reconstruct the energy of weakly decaying b-hadrons, Eweak B ...
