abstract

We perform high-statistics simulations to study the impacts of nuclear structure on the ratios of anisotropic flow observables in $^{208}$Pb+$^{208}$Pb and $^{129}$Xe+$^{129}$Xe collisions at the Large Hadron Collider. Even with $40\%$ difference in atomic numbers between $^{208}$Pb and $^{129}$Xe nuclei, the ratios of anisotropic flow in the same centrality class between the two collision systems are strongly affected by the nuclear structure inputs in the initial state. The ratios of $v_2\{4\}/v_2\{2\}$ in these collisions are sensitive to the nuclear skin thickness of the colliding nuclei, providing indirect constraints on the nuclei's neutron skin. Our model predictions serve as a benchmark to compare with experimental measurements.

  1. A Resummed Hydrodynamic Description of Relativistic Heavy-ion Collisions

    nucl-th 2025-08 conditional novelty 6.0 of 10

    A resummed hydrodynamic scheme with tunable caps on shear and bulk viscous stress is introduced; it reduces to standard second-order hydrodynamics for small stresses and is used to quantify flow-observable uncertainti...

  2. Correlation between particle spectra and elliptic flow

    nucl-th 2025-06 conditional novelty 6.0 of 10

    A new three-particle observable, v02(pT), correlates the hadron spectrum with elliptic flow and is predicted to show a mass-ordering inversion at low pT in Pb+Pb collisions.

  3. Nonlinear collective flow reveals the breakdown of quadrupole--hexadecapole scaling in heavy ion collisions

    nucl-th 2026-07 conditional novelty 5.0 of 10

    The nonlinear flow coefficient ξ6,222 in simulated U+U collisions separates the four (β2, β4) nuclear topology classes, making the sign of the hexadecapole deformation β4 experimentally accessible.
