Selected Experimental Results from Heavy-Ion Collisions at LHC

Abstract EN

We review a subset of experimental results from the heavy-ion collisions at the Large Hadron Collider (LHC) facility at CERN.

Excellent consistency is observed across all the experiments at the LHC (at center of mass energy sNN=2.76 TeV) for the measurements such as charged particle multiplicity density, azimuthal anisotropy coefficients, and nuclear modification factor of charged hadrons.

Comparison to similar measurements from the Relativistic Heavy Ion Collider (RHIC) at lower energy (sNN=200 GeV) suggests that the system formed at LHC has a higher energy density and larger system size and lives for a longer time.

These measurements are compared to model calculations to obtain physical insights on the properties of matter created at the RHIC and LHC.
