TL;DR: The Large Ion Collider Experiment (ALICE) as discussed by the authors is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model.

TL;DR: A large acceptance Electromagnetic Calorimeter (EMCal) was installed in the ALICE central detector to enhance the capabilities for jet quenching measurements as mentioned in this paper, which has played a key role at the Relativistic Heavy Ion Collider (RHIC) and will be central to the study of nuclear collisions.

TL;DR: In this paper, the future opportunities for high-density QCD studies with ion and proton beams at the LHC are presented, and four major scientific goals are identified: the characterisation of the macroscopic long wavelength Quark-Gluon Plasma (QGP) properties with unprecedented precision, the investigation of the microscopic parton dynamics underlying QGP properties, the development of a unified picture of particle production and QCD dynamics from small (pp) to large (nucleus--nucus) systems, the exploration of parton densities in nuclei in

TL;DR: In this article, the ALICE Experiment was upgraded to make high precision measurements of rare probes at low pT, which cannot be selected with a trigger, and therefore require a very large sample of events recorded on tape.
