Probing spectral properties of the QGP with real-time lattice simulations / Boguslavski, Kirill (Jyvaskyla U.) ; Kurkela, Aleksi (CERN ; Stavanger U.) ; Lappi, Tuomas (Helsinki U. ; Jyvaskyla U.) ; Peuron, Jarkko (ECT, Trento ; Fond. Bruno Kessler, Trento)
We present a new method to obtain spectral properties of a non-Abelian gauge theory in the region where occupation numbers are high. The method to measure the (single-particle) spectral function is based on linear response theory and classical-statistical lattice simulations. [...]

Plasmon mass scale and quantum fluctuations of classical fields on a real time lattice / Kurkela, Aleksi (CERN ; Stavanger U.) ; Peuron, Jarkko (Jyvaskyla U.) ; Lappi, Tuomas (Helsinki Inst. of Phys. ; Jyvaskyla U.)
Classical real-time lattice simulations play an important role in understanding non-equilibrium phenomena in gauge theories and are used in particular to model the prethermal evolution of heavy-ion collisions. Above the Debye scale the classical Yang-Mills (CYM) theory can be matched smoothly to kinetic theory. [...]

Predictions for cold nuclear matter effects on charged hadrons, identified light hadrons, quarkonium and heavy flavor hadrons, Drell-Yan dileptons, jets, photons, gauge bosons and top quarks produced in $p+$Pb collisions at $\sqrt{s_{_{NN}}} = 8.16$ TeV are compiled and, where possible, compared to each other. Predictions of the normalized ratios of $p+$Pb to $p+p$ cross sections are also presented for most of the observables, providing new insights into the expected role of cold nuclear matter effects.

Time evolution of linearized gauge field fluctuations on a real-time lattice / Kurkela, Aleksi (CERN ; Stavanger U.) ; Lappi, Tuomas (Jyvaskyla U. ; Helsinki Inst. of Phys.) ; Peuron, Jarkko (Jyvaskyla U.)
Classical real-time lattice simulations play an important role in understanding non-equilibrium phenomena in gauge theories and are used in particular to model the prethermal evolution of heavy-ion collisions. Due to instabilities, small quantum fluctuations on top of the classical background may significantly affect the dynamics of the system. [...]

High energy factorization in nucleus-nucleus collisions III. Long range rapidity correlations / Gelis, Francois (CERN ; DSM, DAPNIA, Saclay) ; Lappi, Tuomas (DSM, DAPNIA, Saclay) ; Venugopalan, Raju (Brookhaven)
We obtain a novel result in QCD for long range rapidity correlations between gluons produced in the collision of saturated high energy hadrons or nuclei. This result, obtained in a high energy factorization framework, provides strong justification for the Glasma flux tube picture of coherent strong color fields. [...]

High energy factorization in nucleus-nucleus collisions II - Multigluon correlations / Gelis, Francois (CERN) ; Lappi, Tuomas (Saclay, SPhT) ; Venugopalan, Raju (Brookhaven)
We extend previous results (arXiv:0804.2630 [hep-ph]) on factorization in high-energy nucleus-nucleus collisions by computing the inclusive multigluon spectrum to next-to-leading order. The factorization formula is strictly valid for multigluon emission in a slice of rapidity of width \Delta Y< 1/\alpha_s. [...]

High energy factorization in nucleus-nucleus collisions, I / Gelis, Francois (CERN) ; Lappi, Tuomas (Saclay, SPhT) ; Venugopalan, Raju (Brookhaven)
We derive a high energy factorization theorem for inclusive gluon production in A+A collisions. Our factorized formula resums i) all order leading logarithms (g^2 \ln(1/x_{1,2}))^n of the incoming partons momentum fractions, and ii) all contributions (g \rho_{1,2})^n that are enhanced when the color charge densities in the two nuclei are of order of the inverse coupling-- \rho_{1,2}\sim g^{-1}.
