We review key measurements performed by CMS in the context of its heavy ion physics
program, using event samples collected in 2010–2018 with several collision systems and …

The bulk motion of nuclear matter at the ultrahigh temperatures created in heavy ion
collisions at the Relativistic Heavy Ion Collider and the Large Hadron Collider is well …

In the hydrodynamic model description of heavy-ion collisions, the elliptic flow v 2 and
triangular flow v 3 are sensitive to the quadrupole deformation β 2 and octupole deformation …

The observation of long-range rapidity correlations among particles in high-multiplicity p–p
and p–Pb collisions has created new opportunities for investigating novel high-density QCD …

Measurements of anisotropic flow coefficients (vn) and their cross-correlations using two-
and multiparticle cumulant methods are reported in collisions of pp at s= 13 TeV, p-Pb at a …

In this review, we present an up-to-date phenomenological summary of research
developments in the physics of the Quark–Gluon Plasma (QGP). A short historical …

In the hydrodynamic framework of heavy-ion collisions, elliptic flow v 2 is sensitive to the
quadrupole deformation β of the colliding ions. This enables one to test whether the …

Most atomic nuclei are deformed with a quadrupole shape described by its overall strength β
2 and triaxiality γ. The deformation can be accessed in high-energy heavy ion collisions by …

High energy heavy ion collisions create quark gluon plasmas that behave like almost perfect
fluids. Very similar features to those that led to this insight have also been observed in …

The elliptic (v 2) and triangular (v 3) azimuthal anisotropy coefficients in central He 3+ Au, d+
Au, and p+ Au collisions at s NN= 200 GeV are measured as a function of transverse …
