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 …

We present a microscopic model for collective effects in high multiplicity proton–proton
collisions, where multiple partonic subcollisions give rise to a dense system of strings. From …

Relativistic hydrodynamics has been quite successful in explaining the collective behaviour
of the QCD matter produced in high energy heavy‐ion collisions at RHIC and LHC. We …

The mass ordering of mean transverse momentum⟨ p T⟩ and of the Fourier harmonic
coefficient v 2 (p T) of azimuthally anisotropic particle distributions in high energy hadron …

We study the radial distribution function of the color sources (strings) formed in hadronic
collisions and the requirements to obtain a liquid. As a repulsive interaction is needed, we …

The" unreasonable effectiveness" of relativistic fluid dynamics in describing high energy
heavy-ion and even proton-proton collisions will be demonstrated and discussed. Several …

Measurements of multiparticle correlations in the collisions of small systems such as p+ p,
p/d/3He+ A show striking similarity to the observations in heavy‐ion collisions. A number of …

Hanbury Brown–Twiss interferometry (HBT) provides crucial insights into both the space-
time structure and the momentum-space evolution of ultrarelativistic nuclear collisions at …

Exact solutions to the equations of hydrodynamics provide valuable benchmark tests for
numerical hydrodynamic codes and also provide useful insights into the nature of …
