Title: Thermal photon anisotropic flow serves as a quark–gluon plasma viscometer

Abstract

calculations of viscous photon emission from nuclear collisions at RHIC and LHC. Thermal photons’ anisotropic flow coefficients vn are computed, both with and without accounting for viscous corrections to the standard thermal emission rates. These corrections are found to have a larger effect on the v_n coefficients than the viscous suppression of hydrodynamic flow anisotropies. For thermal photons, the ratio v₂{SP}/_v3{SP} shows stronger sensitivity to the quark-gluon plasma (QGP) shear viscosity than for hadrons, and it can thus serve as a sensitive QGP viscometer.

Anisotropic flow of thermal photons as a quark-gluon plasma viscometer

Journal Article Shen, Chun ; Heinz, Ulrich ; Paquet, Jean-François ; ... - Physical Review C, Nuclear Physics

We present state-of-the-art calculations of viscous photon emission from nuclear collisions at the BNL Relativistic Heavy Ion Collider (RHIC) and the CERN Large Hadron Collider (LHC). Fluctuating initial density profiles are evolved with event-by-event viscous hydrodynamics. Momentum spectra of thermal photons radiated by these explosively expanding fireballs and their p_T-differential anisotropic flow coefficients v_n (p_T) are computed, both with and without accounting for viscous corrections to the standard thermal emission rates. Viscous corrections to the rates are found to have a larger effect on the v n coefficients than the viscous suppression of hydrodynamic flow anisotropies. The benefits of takingmore »« less

Photon production and elliptic flow from a momentum-anisotropic quark-gluon plasma

Journal Article Kasmaei, Babak S. ; Strickland, Michael - Physical Review D

The emission of real photons from a momentum-anisotropic quark-gluon plasma (QGP) is affected by both the collective flow of the radiating medium and the modification of the local rest frame emission rate due to the anisotropic momentum distribution of partonic degrees of freedom. In this paper, we first calculate the photon production rate from an ellipsoidally momentum-anisotropic QGP including hard contributions from Compton scattering and quark pair annihilation and soft contribution calculated using the hard thermal loop approximation. We introduce a parametrization of the nonequilibrium rate in order to facilitate its further application in yield and flow calculations. We convolve the anisotropic photon rate with the space-time evolution of QGP provided by 3 + 1d anisotropic hydrodynamics to obtain the yield and the elliptic flow coefficientmore »« less

Photon emission from a momentum-anisotropic quark-gluon plasma

Journal Article Shen, Chun ; Paquet, Jean-François ; Heinz, Ulrich ; ... - Physical Review C, Nuclear Physics

Here, we compute the photon emission rate from a quark-gluon plasma with an anisotropic particle momentum distribution induced by a non-vanishing local shear pressure tensor. Our calculation includes photon production through Compton scattering and quark-antiquark annihilation at leading order in αs , with all off-equilibrium corrections to leading order in the momentum anisotropy. For fermions we prove that the Kubo-Martin-Schwinger relation holds in the hard loop regime for any particle momentum distribution function that is reflection symmetric. This supports the equivalence, for 2-to-2 scattering processes, of the diagrammatic and kinetic approaches to calculating the photon emission rate. We compare themore »« less

200 A GeV Au+Au Collisions Serve a Nearly Perfect Quark-Gluon Liquid

Journal Article Huichao, Song ; Department of Physics, Ohio State University, Columbus, Ohio 43210 ; Bass, Steffen A ; ... - Physical Review Letters

A new robust method to extract the specific shear viscosity ({eta}/s){sub QGP} of a quark-gluon plasma (QGP) at temperatures T{sub c}<T < or approx. 2T{sub c} from the centrality dependence of the eccentricity-scaled elliptic flow v{sub 2}/{epsilon} measured in ultrarelativistic heavy-ion collisions is presented. Coupling viscous fluid dynamics for the QGP with a microscopic transport model for hadronic freeze-out we find for 200 A GeV Au+Au collisions that v{sub 2}/{epsilon} is a universal function of multiplicity density (1/S)(dN{sub ch}/dy) that depends only on the viscosity but not on the model used for computing the initial fireball eccentricity {epsilon}.

Heavy-quark probes of the quark-gluon plasma and interpretation of recent data taken at the BNL Relativistic Heavy Ion Collider

Journal Article Hees, Hendrik van ; Rapp, Ralf ; Greco, Vincenzo - Physical Review. C, Nuclear Physics

Thermalization and collective flow of charm (c) and bottom (b) quarks in ultrarelativistic heavy-ion collisions are evaluated based on elastic parton rescattering in an expanding quark-gluon plasma (QGP). We show that resonant interactions in a strongly interacting QGP (sQGP), as well as parton coalescence, can play an essential role in the interpretation of recent data from the BNL Relativistic Heavy-Ion Collider (RHIC), and thus illuminate the nature of the sQGP and its hadronization. Our main assumption, motivated by recent findings in lattice quantum chromodynamics, is the existence of D- and B-meson states in the sQGP, providing resonant cross sections formore »« less
