Title: Second-Order Hydrodynamics in Next-to-Leading-Order QCD

Abstract

We compute the hydrodynamic relaxation times τ_π and τ_j for hot QCD at next-to-leading order in the coupling with kinetic theory. We show that certain dimensionless ratios of second-order to first-order transport coefficients obey bounds which apply whenever a kinetic theory description is possible; the computed values lie somewhat above these bounds. Strongly coupled theories with holographic duals strongly violate these bounds, highlighting their distance from a quasiparticle description.

Light-Front Holographic QCD

Conference Brodsky, Stanley J ; /SLAC /Southern Denmark U., CP3-Origins ; de Teramond, Guy F ; ...

The relation between the hadronic short-distance constituent quark and gluon particle limit and the long-range confining domain is yet one of the most challenging aspects of particle physics due to the strong coupling nature of Quantum Chromodynamics, the fundamental theory of the strong interactions. The central question is how one can compute hadronic properties from first principles; i.e., directly from the QCD Lagrangian. The most successful theoretical approach thus far has been to quantize QCD on discrete lattices in Euclidean space-time. Lattice numerical results follow from computation of frame-dependent moments of distributions in Euclidean space and dynamical observables in Minkowskimore »« less

B{sup -}{yields}{pi}{sup -}{pi}{sup 0}/{rho}{sup -}{rho}{sup 0} to next-to-next-to-leading order in QCD factorization

Journal Article Bell, Guido ; Pilipp, Volker - Physical Review. D, Particles Fields

The approximate tree decays B{sup -}{yields}{pi}{sup -}{pi}{sup 0}/{rho}{sup -}{rho}{sup 0} may serve as benchmark channels for testing the various theoretical descriptions of the strong interaction dynamics in hadronic B meson decays. The ratios of hadronic and differential semileptonic B{yields}{pi}l{nu}/{rho}l{nu} decay rates at maximum recoil provide particularly clean probes of the QCD dynamics. We confront the recent next-to-next-to-leading order calculation in the QCD factorization framework with experimental data and find support for the factorization assumption. A detailed analysis of all tree-dominated B{yields}{pi}{pi}/{pi}{rho}/{rho}{rho} decay modes seems to favor somewhat enhanced color-suppressed amplitudes, which may be accommodated in QCD factorization by a smallmore »« less

Flavor Changing Neutral Coupling Mediated Radiative Top Quark Decays at Next-to-Leading Order in QCD

Journal Article Drobnak, Jure ; Kamenik, Jernej F ; Fajfer, Svjetlana ; ... - Physical Review Letters

We compute the branching ratios for the rare top quark decays t{yields}c{gamma} and t{yields}cZ mediated by effective flavor changing neutral couplings at next-to-leading order in QCD, including the effects due to operator mixing. After resumming contributions of the order of [{alpha}{sub s}log({Lambda}/m{sub t})]{sup n}, where {Lambda} is the scale at which the effective operators are generated, using renormalization group methods, we compute finite matrix element corrections and study the effects of experimental kinematic cuts on the extracted branching ratios. We find that the t{yields}c{gamma} decay can also be used to probe the effective operators mediating t{yields}cg processes, since the lattermore »« less

Heavy Quark Diffusion in Perturbative QCD at Next-to-Leading Order

Journal Article Caron-Huot, Simon ; Moore, Guy D - Physical Review Letters

We compute the momentum diffusion coefficient of a heavy quark in a hot QCD plasma, to next-to-leading order in the weak-coupling expansion. Corrections arise at O(g{sub s}); physically they represent interference between overlapping scatterings, as well as soft, electric scale (p{approx}gT) gauge field physics, which we treat using the hard thermal loop effective theory. In 3-color, 3-flavor QCD, the momentum diffusion constant of a fundamental representation heavy quark at next-to-leading order is {kappa}=(16{pi}/3){alpha}{sub s}{sup 2}T{sup 3}(ln(1/g{sub s})+0.07428+1.9026g{sub s}). The convergence of the perturbative expansion is poor.

Single-Inclusive Jet Production In Electron-Nucleon Collisions Through Next-To-Next-To-Leading Order In Perturbative QCD

Journal Article Abelof, Gabriel ; Boughezal, Radja ; Liu, Xiaohui ; ... - Physics Letters. Section B

We compute the Oσ²σ²_s perturbative corrections to inclusive jet production in electron-nucleon collisions. This process is of particular interest to the physics program of a future Electron Ion Collider (EIC). We include all relevant partonic processes, including deep-inelastic scattering contributions, photon-initiated corrections, and parton-parton scattering terms that first appear at this order. Upon integration over the final-state hadronic phase space we validate our results for the deep-inelastic corrections against the known next-to-next-to-leading order (NNLO) structure functions. Our calculation uses the N-jettiness subtraction scheme for performing higher-order computations, and allows for a completely differential description of the deep-inelastic scattering process.
