We present an extended Bayesian analysis using Trajectum where the initial condition can now include binary scaling. For the far-from-equilibrium evolution before hydrodynamics we introduce an interpolation between free streaming and a holographically inspired evolution that exhibits fast hydrodynamization. We find strong evidence that binary scaling is incompatible with experimental data and find evidence that the holographic far-from-equilibrium evolution is preferred. We end with a discussion on several changes and improvements in the Bayesian framework.

  1. Yoctosecond imaging of the ground state of $^{129}$Xe at the Large Hadron Collider

    nucl-th 2026-06 unverdicted novelty 6.0

    Bayesian global fit to Xe-Xe and Pb-Pb LHC data infers nearly maximal triaxiality for the 129Xe ground state and extracts two- and three-particle correlations.

  2. The size of the quark-gluon plasma in ultracentral collisions: impact of initial density fluctuations on the average transverse momentum

    nucl-th 2025-11 unverdicted novelty 5.0

    Volume variation with multiplicity in ultracentral collisions is small when total entropy scales with nuclear mass number, as shown by relating it to initial density fluctuation profiles.

  3. Towards a topological data analysis for heavy-ion collisions

    nucl-th 2025-09 conditional novelty 5.0

    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 ...

    nucl-th 2026-06 unverdicted novelty 4.0

    Box and expanding simulations with SMASH extended to 2-to-3 quark processes show energy spectrum thermalizes by ~0.2 fm/c, momentum isotropizes by ~2 fm/c, but chemical equilibration remains incomplete by 5 fm/c and h...
