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: The ALICE Collaboration as mentioned in this paper is a general-purpose heavy-ion experiment designed to study the physics of strongly interacting matter and the quark-gluon plasma in nucleus-nucleus collisions at the LHC.

TL;DR: HADES as discussed by the authors is a versatile magnetic spectrometer aimed at studying dielectron production in pion, proton and heavy-ion-induced collisions, which includes a ring imaging gas Cherenkov detector for electron-hadron discrimination, a tracking system consisting of a set of 6 superconducting coils producing a toroidal field and drift chambers, and a multiplicity and electron trigger array for additional electron hadron discrimination.

TL;DR: In this paper, the emission of e+ e- pairs from C + C collisions at an incident energy of 1 GeV per nucleon has been investigated, and measured production probabilities, spanning from the π0-Dalitz to the ρ / ω invariant mass region, display a strong excess above the cocktail of standard hadronic sources.

TL;DR: In this article, the electron pairs were reconstructed for n + p reactions by detecting the proton spectator from the deuteron breakup with the HADES spectrometer, and the yield of electron pairs with invariant mass M e + e − > 0.15 GeV / c 2 was found to be an order of magnitude larger in N + P reactions as compared to N + p.
