At the end of 2010, the Large Hadron Collider (LHC) at CERN started operation with heavy-
ion beams, colliding lead nuclei at a center-of-mass energy of 2.76 TeV per nucleon. These …

Heavy ion collisions quickly form a droplet of quark–gluon plasma (QGP) with a remarkably
small viscosity. We give an accessible introduction to how to study this smallest and hottest …

Direct photon production at mid-rapidity in Pb–Pb collisions at s NN= 2.76 TeV was studied
in the transverse momentum range 0.9< p T< 14 GeV/c. Photons were detected with the …

In this paper measurements are presented of π±, K±, p, and p¯ production at midrapidity (|
y|< 0.5), in Pb-Pb collisions at s NN= 2.76 TeV as a function of centrality. The measurement …

This publication describes the methods used to measure the centrality of inelastic Pb-Pb
collisions at a center-of-mass energy of 2.76 TeV per colliding nucleon pair with ALICE. The …

The physics programme and the design are described of a new collider for particle and
nuclear physics, the Large Hadron Electron Collider (LHeC), in which a newly built electron …

We introduce an event-by-event perturbative-QCD+ saturation+ hydro (“EKRT”) framework
for ultrarelativistic heavy-ion collisions, where we compute the produced fluctuating QCD …

Heavy ion collision experiments recreating the quark-gluon plasma that filled the nascent
universe have established that it is a nearly perfect liquid that flows with such minimal …

The production of Ξ− and Ω− baryons and their anti-particles in Pb–Pb collisions at s NN=
2.76 TeV has been measured using the ALICE detector. The transverse momentum spectra …

The inclusive transverse momentum (p T) distributions of primary charged particles are
measured in the pseudo-rapidity range| η|< 0.8 as a function of event centrality in Pb–Pb …
