The chiral magnetic effect (CME) is predicted to occur as a consequence of a local violation of P and CP symmetries of the strong interaction amidst a strong electromagnetic field generated in relativistic heavy-ion collisions. Experimental manifestation of the CME involves a separation of positively and negatively charged hadrons along the direction of the magnetic field. Previous measurements of the CME-sensitive charge-separation observables remain inconclusive because of large background contributions. To better control the influence of signal and backgrounds, the STAR Collaboration performed a blind analysis of a large data sample of approximately 3.8 billion isobar collisions of 9644Ru+9644Ru and 9640Zr+9640Zr at √sNN=200 GeV. Prior to the blind analysis, the CME signatures are predefined as a significant excess of the CME-sensitive observables in Ru+Ru collisions over those in Zr+Zr collisions, owing to a larger magnetic field in the former. A precision down to 0.4% is achieved, as anticipated, in the relative magnitudes of the pertinent observables between the two isobar systems. Observed differences in the multiplicity and flow harmonics at the matching centrality indicate that the magnitude of the CME background is different between the two species. No CME signature that satisfies the predefined criteria has been observed in isobar collisions in this blind analysis.

The ALICE Collaboration reports unique data on particle production in Pb-Pb and inelastic $p$-$p$ collisions at the LHC at 5.02 TeV. The measurements range from very peripheral to the most central collisions, and cover particles with transverse momenta from hundreds of MeV/$c$ to 20 GeV/$c$. The precision and breadth of the data provide tight constraints on our understanding of particle production mechanisms in these collisions.

The Large Hadron Collider (LHC) at CERN will extend the frontiers of particle physics with its \nunprecedented high energy and luminosity. Inside the LHC, bunches of up to 1011 protons (p) \nwill collide 40 million times per second to provide 14 TeV proton-proton collisions at a design \nluminosity of 1034 cm2s1. The LHC will also collide heavy ions (A), in particular lead nuclei, at \n5.5 TeV per nucleon pair, at a design luminosity of 1027 cm2s1. \nThe high interaction rates, radiation doses, particle multiplicities and energies, as well as the \nrequirements for precision measurements have set new standards for the design of particle detectors. \nTwo general purpose detectors, ATLAS (A Toroidal LHC ApparatuS) and CMS (Compact \nMuon Solenoid) have been built for probing p-p and A-A collisions. \nThis paper presents a comprehensive overview of the ATLAS detector prior to the first LHC \ncollisions, written as the installation of the ATLAS detector is nearing completion. This detector \nrepresents the work of a large collaboration of several thousand physicists, engineers, technicians, \nand students over a period of fifteen years of dedicated design, development, fabrication, and installation.
