Gyulassy Miklós (Prof. emeritus, MTA Wigner FK, Columbia University): Precision Dijet Acoplanarity Tomography of the Chromo Structure of Perfect QCD Fluids

Europe/Budapest
Description

Dijet azimuthal acoplanarity is dominated by vacuum pQCD radiation
always associated with hard jet production. Jet-medium interactions
broaden the vacuum Sudakov azimuthal angle distributions. In the
Gaussian approximation (A.H.Mueller et al 2016) the broadening rms
depends only on the jet path L averaged transport coefficient q̂ . We
focus on the rarer non-Gaussian “Landau tail” finite scattering induced
fluctuations that are more sensitive to the detailed microscopic
chromo-electric and chromo-magnetic structure of prefect QCD fluids. We
estimate the magnitude of experimental precision needed in future dijet
experiments to discriminate between perturbative QCD/HTL screened color
electric q+g color structure and possible non-perturbative color
bleached semi-QGP plus emergent magnetic Monopole (sQGMP) color
structure of QCD perfect fluids using a new event by event version,
CIBJET (S.Shi et al 2018), of the CUJET3 (JHEP 1602 (2016) 169)
framework that combines ebe viscous hydro with finite opacity medium
induced jet energy loss.
