“…On the experimental side, the elliptic flow observable v 2 , which is sensitive to the value of η in units of entropy density s, is now corrected for non-medium-generated two-particle correlations [12]. The conclusion that η/s must be much smaller than unity has so far withstood these refinements of heavy-ion phenomenology [11].…”

“…This early agreement between ideal hydrodynamics and experiment has been refined in recent times. On the theory side, the dissipative effects of shear viscosity η have been included in full 3d hydrodynamics calculations [8,9,10] and the sensitivity to initial conditions quantitatively estimated [11] for the first time. On the experimental side, the elliptic flow observable v 2 , which is sensitive to the value of η in units of entropy density s, is now corrected for non-medium-generated two-particle correlations [12].…”

Collective flow has been observed in heavy ion collisions, with a large anisotropic component, and ideal hydrodynamic calculations had significant successful in describing the distribution of produced particles at the RHIC experiments. In order to account for this near ideal fluid behavior, the shear and bulk viscosity of the quark gluon plasma (QGP) must be computed from first principles in a regime where the QGP is not weakly coupled. In this talk I describe recent progress in computing energy-momentum tensor correlators on the lattice from which the viscosities can be extracted via Kubo formulas. I also show how to cumulate information from several channels, including at non-vanishing spatial momentum, in order to best constrain the viscosities. These methods should soon yield predictions at the higher temperatures that will be explored at the LHC experiments.

“…The study of these collisions at the Relativistic Heavy Ion Collider (RHIC) and at the Large Hadron Collider (LHC) has demonstrated that matter at temperatures above the crossover between hot hadronic matter and hotter QGP exhibits strong collective phenomena [1][2][3][4][5][6][7] which can be described successfully by hydrodynamic simulations of the rapid expansion and cooling of the initially lumpy droplets of matter produced in the collisions [8][9][10][11][12][13][14][15][16][17][18]. Such strong collectivity has also recently been observed in smaller colliding systems, including p-Pb, p-p or 3 He-Au [19][20][21][22][23][24][25][26][27][28][29], for which hydrodynamic simulations also seem to be successful [30][31][32][33][34][35][36][37].…”

Within the context of a hybrid strong/weak coupling model of jet quenching, we study the modification of the angular distribution of the energy within jets in heavy ion collisions, as partons within jet showers lose energy and get kicked as they traverse the strongly coupled plasma produced in the collision. To describe the dynamics transverse to the jet axis, we add the effects of transverse momentum broadening into our hybrid construction, introducing a parameter K ≡q/T 3 that governs its magnitude. We show that, because of the quenching of the energy of partons within a jet, even when K = 0 the jets that survive with some specified energy in the final state are narrower than jets with that energy in proton-proton collisions. For this reason, many standard observables are rather insensitive to K. We propose a new differential jet shape ratio observable in which the effects of transverse momentum broadening are apparent. We also analyze the response of the medium to the passage of the jet through it, noting that the momentum

“…The most prominent example of such a universal property is the ratio of shear viscosity η over entropy density s [24] which is known to obey η/s = 1/4π for any strongly coupled theory with a two-derivative gravity dual and unbroken SO(3) rotational symmetry [22,[25][26][27][28][29][30][31][32]. Current estimates for the value of η/s in the QGP extracted from heavy ion collision data are indeed close to 1/4π [33][34][35][36][37][38][39].…”

We study second-order hydrodynamic transport in strongly coupled non-conformal field theories with holographic gravity duals in asymptotically anti-de Sitter space. We first derive new Kubo formulae for five second-order transport coefficients in nonconformal fluids in (3 + 1) dimensions. We then apply them to holographic RG flows induced by scalar operators of dimension ∆ = 3. For general background solutions of the dual bulk geometry, we find explicit expressions for the five transport coefficients at infinite coupling and show that a specific combination,H = 2ητ π − 2 (κ − κ * ) − λ 2 , always vanishes. We prove analytically that the Haack-Yarom identity H = 2ητ π − 4λ 1 − λ 2 = 0, which is known to be true for conformal holographic fluids at infinite coupling, also holds when taking into account leading non-conformal corrections. The numerical results we obtain for two specific families of RG flows suggest that H vanishes regardless of conformal symmetry. Our work provides further evidence that the Haack-Yarom identity H = 0 may be universally satisfied by strongly coupled fluids.
