Abstract

These proceedings provide an overview of the new results obtained with the ATLAS detector at the LHC, which were presented in the Quark Matter 2017 conference. These results were covered by twelve parallel talks, one flash talk and eleven posters. These proceedings group these results into five areas: initial state, jet quenching, quarkonium production, longitudinal flow dynamics, and collectivity in small systems.

Highlights

  • In order to reliably extract the properties of the Quark Gluon Plasma (QGP) created in heavy ion collisions at the LHC, one needs to first achieve a detailed understanding of the space-time evolution of the system

  • ATLAS showed many new results obtained from high statistics pp data at 2.76, 5.02 and 13 TeV, p+Pb data at 5.02 and 8.16 TeV, as well as Pb+Pb data at 2.76 and 5.02 TeV, collected in the Run 1 (2010–2013) and Run 2 (2015–2016) periods

  • These results range from constraining the initial state of the heavy ion collisions, to understanding the interaction of the hard probes with the QGP and the longitudinal expansion of the QGP, and to the clarification of the origin of collective behavior in small collision systems

Summary

Introduction

In order to reliably extract the properties of the Quark Gluon Plasma (QGP) created in heavy ion collisions at the LHC, one needs to first achieve a detailed understanding of the space-time evolution of the system This requires improving the precision of the measurements on existing observables, exploring new observables, as well as studying the dependence on the type of collision systems or the collision energies. ATLAS showed many new results obtained from high statistics pp data at 2.76, 5.02 and 13 TeV, p+Pb data at 5.02 and 8.16 TeV, as well as Pb+Pb data at 2.76 and 5.02 TeV, collected in the Run 1 (2010–2013) and Run 2 (2015–2016) periods These results range from constraining the initial state of the heavy ion collisions, to understanding the interaction of the hard probes with the QGP and the longitudinal expansion of the QGP, and to the clarification of the origin of collective behavior in small collision systems
