abstract
The event-by-event multiplicity distribution, the energy densities and energy density weighted eccentricity moments epsilon_n (up to n=6) at early times in heavy-ion collisions at both RHIC (root-s=200 GeV) and LHC (root-s=2.76 TeV) are computed in the IP-Glasma model. This framework combines the impact parameter dependent saturation model (IP-Sat) for nucleon parton distributions (constrained by HERA deeply inelastic scattering data) with an event-by-event classical Yang-Mills description of early-time gluon fields in heavy-ion collisions. The model produces multiplicity distributions that are convolutions of negative binomial distributions without further assumptions or parameters. The eccentricity moments are compared to the MC-KLN model; a noteworthy feature is that fluctuation dominated odd moments are consistently larger than in the MC-KLN model.

Thermal dilepton polarization in LHC heavy-ion collisions is sensitive to QGP in-medium properties, with a one-to-one mapping derived between dielectron and dimuon channels.
Global analysis of HERA DIS and ALICE Pb+Pb data using saturation initial-state model determines early-time non-equilibrium η/s of QGP.
Bayesian posteriors from JETSCAPE jet-quenching model are largely compatible across centrality but exhibit shifts across beam energy and observable class, with varying ability to predict complementary datasets.
MC-CGC simulations with rcBK evolution favor HERA-tuned MV^γ and MV^e initial conditions for LHCb forward hadron data, show kT factorization outperforming DHJ at mid-rapidity, and provide predictions for ALICE FoCal neutral mesons and jets.
Accounting for prompt photons in a viscous hydrodynamic model of Au+Au collisions explains the measured v2 and v3 of direct photons, with good agreement in mid-central collisions but centrality-dependent discrepancies.
