We introduce a global analysis of relativistic heavy ion collisions using Trajectum of a significantly higher precision and including a new option to vary the normalization of the centrality estimator. We use the posterior distribution of our parameters to generate a set of high statistics samples that allows us to make precise predictions including statistical and systematic uncertainties estimated from the model parameter distribution. The results are systematically compared with experiment whereby we also include many observables not included in the global analysis. This includes in particular (extremely) ultracentral anisotropic flow and mean transverse momentum, whereby we find satisfactory agreement with experiment where data is available. Lastly, we compute spectra and anisotropic flow for oxygen-oxygen collisions performed at RHIC and to be performed at the LHC and comment on how these collisions may inform us on properties of the Quark-Gluon-Plasma.

Evidence of nuclear geometry-driven anisotropic flow in OO and Ne$-$Ne collisions at $\mathbf{\sqrt{{\textit s}_{\rm\mathbf {NN}}}}$ = 5.36 TeV
First measurements of elliptic and triangular flow in OO and Ne-Ne collisions show geometry-driven collectivity consistent with hydrodynamic predictions.

Measurement of the azimuthal anisotropy of charged particles in $\sqrt{s_{\mathrm{NN}}}=5.36$ TeV $^{16}$O$+^{16}$O and $^{20}$Ne$+^{20}$Ne collisions with the ATLAS detector
First measurements of v_n (n=2-4) in 5.36 TeV O+O and Ne+Ne collisions show enhanced v2 in central neon collisions consistent with prolate nuclear deformation.

Momentum Broadening in the Opacity Expansion: All-Path-Length Corrections and Improved Regge Kinematics
Combined short-path-length (APL) and sub-eikonal corrections to GLV momentum broadening nearly cancel, restoring the standard GLV result; the paper argues this may resolve the earlier large negative APL energy-loss co...

Wounded parton scaling of multiplicities in ultra-relativistic light- and heavy-ion collisions
With four partons per nucleon and one shared entropy-to-multiplicity scale, a wounded-parton Glauber model with negative-binomial fluctuations fits O+O, Ne+Ne, Xe+Xe, and Pb+Pb multiplicity distributions from 1–80% ce...

Towards a topological data analysis for heavy-ion collisions
Persistent homology Betti curves and persistence distributions for Trajectum Pb-Pb and O-O events are robust and reflect known flow and multiplicity phenomenology, with no enhanced parameter sensitivity over standard ...

Nuclear Physics Confronts Relativistic Collisions Of Isobars
RHIC isobar data are explained by different shapes of 96Ru and 96Zr, with 96Zr showing a large octupole deformation, so nuclear structure uncertainty, not the magnetic field, dominates the observed ratios.
