Measurement of the centrality dependence of J/psi yields and observation of Z production in lead-lead collisions with the ATLAS detector at the LHC
(Physics Letters B, 2011)
Using the ATLAS detector, a centrality-dependent suppression has been observed in the yield of J/psi mesons produced in the collisions of lead ions at the Large Hadron Collider. In a sample of minimum-bias lead-lead ...
Suppression of charged particle production at large transverse momentum in central Pb-Pb collisions at root s(NN)=2.76 TeV
(Physics Letters B, 2011)
Inclusive transverse momentum spectra of primary charged particles in Pb-Pb collisions at root s(NN) = 2.76 TeV have been measured by the ALICE Collaboration at the LHC. The data are presented for central and peripheral ...
Measurement of the ratio of the 3-jet to 2-jet cross sections in pp collisions at root s=7 TeV
(Physics Letters B, 2011)
A measurement of the ratio of the inclusive 3-jet to 2-jet cross sections as a function of the total jet transverse momentum. HT, in the range 0.2 LT H-T LT 2.5 TeV is presented. The data have been collected at a proton-proton ...
Search for the Standard Model Higgs boson in the two photon decay channel with the ATLAS detector at the LHC
(Physics Letters B, 2011)
A search for the Standard Model Higgs boson in the two photon decay channel is reported, using 1.08 fb(-1) of proton-proton collision data at a centre-of-mass energy of 7 TeV recorded by the ATLAS detector. No significant ...
