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

ATLAS Results on Pb+Pb Collisions

A wide research program provided by heavy ion collisions is ongoing at the Large Hadron Col-lider with the aim of studying the properties of QCD matter at extreme temperatures and densities. The large acceptance and high granularity of the ATLAS Detector is well suited to perform detailed analyses on bulk phenomena, jets and leptonic probes. Measurements of these observables provided by the 9 µ...

Measurement of multi-particle azimuthal correlations in pp, p + Pb and low-multiplicity Pb + Pb collisions with the ATLAS detector

Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in pp collisions at √ s = 5.02 and 13 TeV and in p + Pb collisions at √ sNN = 5.02 TeV, and compared to the results obtained for low-multiplicity Pb + Pb collisions at √ sNN = 2.76 TeV. These measurements aim to assess the collective nature of particle production. The...
