We present an overview of the results obtained in pPb and PbPb collisions at
the Large Hadron Collider during Run 1. We first discuss the results for global
characteristics: cross sections, hadron multiplicities, azimuthal asymmetries,
correlations at low transverse momentum, hadrochemistry, and femtoscopy. We
then review hard and electromagnetic probes: particles with high transverse
momentum, jets, heavy quarks, quarkonium, electroweak bosons and high
transverse momentum photons, low transverse momentum photons and dileptons, and
ultraperipheral collisions. We mainly focus on the experimental results, and
present very briefly the main current theoretical explanations.Comment: 33 pages, 29 figure
