Description
Physics studies of p+Pb and Pb+Pb collisions in the ATLAS experiment at the LHC
at low transverse momenta include the charged particle multiplicities, their scaling
with the number of participating nucleons as well as pT-spectra and their modification
with respect to the spectra of proton-proton collisions. Recent ATLAS results on the total
charged particle multiplicities and spectra in p+Pb and Pb+Pb will be reviewed.
The collective phenomena arising from the azimuthal asymmetry in the initial shape of the interaction region
and maintained by the subsequent system evolution and can be in detail studied by analyzing charged particle
azimuthal distributions. The recent measurements of flow harmonics in p+Pb and Pb+Pb collisions will be presented.
In particular, the presentation will focus on flow harmonics fluctuations and their relation to fluctuations in
the initial state of Pb+Pb collisions.
