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 droplet of liquid made on earth and why it is so interesting. The physics of heavy ions ranges from highly energetic quarks and gluons described by perturbative QCD to a bath of strongly interacting gluons at lower energy scales. These gluons quickly thermalize and form QGP, while the energetic partons traverse… Expand

Transverse Momentum Differential Global Analysis of Heavy-Ion Collisions.
TLDR
In this extended model the QGP bulk viscosity is small and even consistent with zero, and the transverse momentum dependence of both the yields and the anisotropic flow coefficients for both PbPb and pPb collisions is compared for identified particles. Expand
Investigations of $p$+Pb Collisions at Perturbative and Non-Perturbative QCD Scales

Evidence for top quark production in nucleus-nucleus collisions
Abstract Droplets of quark-gluon plasma (QGP), an exotic state of strongly interacting quantum chromodynamics (QCD) matter, are routinely produced in heavy nuclei high-energy collisions. Although theExpand
Evidence for Top Quark Production in Nucleus-Nucleus Collisions.
TLDR
The first evidence for the production of top quarks in nucleus-nucleus collisions is reported, using lead-lead collision data at a nucleon- nucleon center-of-mass energy of 5.02 TeV recorded by the CMS experiment. Expand
Hot Dense Matter: Deconfinement and Clustering of Color Sources in Nuclear Collisions
Within the first few microseconds from after the Big Bang, the hot dense matter was in the form of the Quark Gluon Plasm (QGP) consisting of free quarks and gluons. By colliding heavy nuclei at RHICExpand
