Abstract: (APS)

High pT>10 GeV elliptic flow, which is experimentally measured via the correlation between soft and hard hadrons, receives competing contributions from event-by-event fluctuations of the low-pT elliptic flow and event-plane angle fluctuations in the soft sector. In this Letter, a proper account of these event-by-event fluctuations in the soft sector, modeled via viscous hydrodynamics, is combined with a jet-energy-loss model to reveal that the positive contribution from low-pT v2 fluctuations overwhelms the negative contributions from event-plane fluctuations. This leads to an enhancement of high-pT>10 GeV elliptic flow in comparison to previous calculations and provides a natural solution to the decade-long high-pT RAA⊗v2 puzzle. We also present the first theoretical calculation of high-pT v3, which is shown to be compatible with current LHC data. Furthermore, we discuss how short-wavelength jet-medium physics can be deconvoluted from the physics of soft, bulk event-by-event flow observables using event-shape engineering techniques.
