Fluctuations of harmonic and radial flow in heavy ion collisions with principal components

We analyze the spectrum of harmonic flow, vn(pT) for n=0–5, in event-by-event hydrodynamic simulations of Pb+Pb collisions at the CERN Large Hadron Collider (sNN=2.76TeV) with principal component analysis (PCA). The PCA procedure finds two dominant …

Subleading harmonic flows in hydrodynamic simulations of heavy ion collisions

We perform a principal component analysis (PCA) of v3(pT) in event-by-event hydrodynamic simulations of Pb+Pb collisions at the Large Hadron Collider (LHC). The PCA procedure identifies two dominant contributions to the two-particle correlation …
