  1. 144. Transverse-momentum-dependent gluon distributions and their evolution towards small x

    Oral

    We study the various transverse-momentum-dependent (TMD) gluon distributions entering the cross section for forward di-jet production in dilute-dense collisions. For each TMD distribution we identify their operator definitions at small $x$ and finite $N_c$ as correlators of Wilson lines. With the result, we show the equivalence between the nearly back-to-back limit of the Color Glass...

  2. 172. Initial conditions for hydrodynamics from weakly coupled pre-equilibrium evolution

    Initial State Physics and Approach to Equilibrium
    Oral

    We use effective kinetic theory to simulate equilibration in heavy-ion collisions. We construct a map for out-of-equilibrium initial state to the energy-momentum tensor at a time when hydrodynamics becomes applicable. We apply this map to IPGlasma initial conditions and demonstrate a smooth transition to hydrodynamics. In a phenomenologically favorable range of $\eta/s$ values, equilibration...

  3. 61. Characterization of the initial state and QGP medium from a combined Bayesian analysis of RHIC and LHC data

    Collective Dynamics
    Oral

    A primary goal of heavy-ion physics is the measurement of the fundamental properties of the quark-gluon plasma (QGP) and the characterization of the initial state that leads to its formation.
    While these properties—such as temperature-dependent transport coefficients—are not directly measurable, they may be quantitatively estimated through computational models of heavy-ion collisions.

  4. 157. Particle production in proton-nucleus collisions beyond leading order

    Initial State Physics and Approach to Equilibrium
    Oral

    The study of particle production in proton-nucleus ($pA$) collisions provides essential
    information about high-density effects (like gluon saturation) in the nuclear wavefunction and offers a benchmark for the corresponding studies in nucleus-nucleus collisions. The cross-sections for particle production in $pA$ can in principle be computed within perturbative QCD, using the framework of the...

  5. 411. System-size dependence of the charged-particle pseudorapidity density distribution at 5.02 TeV with ALICE

    Initial State Physics and Approach to Equilibrium
    Oral

    The dependence of particle production on the size of the colliding system (pp, p-Pb, and Pb-Pb) is studied using the most recent measurements at $\sqrt{s_{\rm{NN}}}=5.02~\rm{TeV}$ from ALICE for -3.4 < η < +5.0 employing the same methodology for the three colliding systems. Comparing particle production between Pb-Pb and p-Pb collisions to pp collisions as a reference over a wide...
