Finding, and not finding, "higher harmonic flows"
Thomas A. Trainor
TL;DR
This paper critically examines claims of higher harmonic flows in heavy-ion collisions, highlighting that perturbative QCD calculations can explain observed structures without invoking new flow phenomena.
Contribution
It challenges recent claims of higher harmonic flows by demonstrating that pQCD calculations account for the observed data.
Findings
pQCD describes the observed structures quantitatively
Claims of higher harmonic flows may be explained without new physics
Analysis methods claiming to find higher flows are scrutinized
Abstract
Certain analysis methods have emerged recently that claim to reveal "higher harmonic flows" in more-central \aa collisions at the RHIC and LHC. But pQCD calculations describe the same structures quantitatively.
