abstract

A Multi-Phase Transport (AMPT) model is used to investigate the efficacy of several flow observables to constrain the initial-state deformation of the Uranium nuclei in U$+$U collisions at nucleon-nucleon center-of-mass energy $\sqrt{\textit{s}_{NN}}$ = 193 GeV. The multiparticle azimuthal cumulant method is used to investigate the sensitivity of (I) a set of quantities that are sensitive to both initial- and final-state effects as well as (II) a set of dimensionless quantities that are more sensitive to initial-state effects to the Uranium nuclei quadrupole shape deformation. We find that the combined use of the flow harmonics, flow fluctuations and correlations, linear and non-linear flow correlations to the quadrangular flow harmonic, and the correlations between elliptic flow and the mean-transverse momentum could serve to constrain the nuclear deformation of the Uranium nuclei. Therefore, a comprehensive set of measurements of such observables can provide a quantifying tool for the quadrupole shape deformation via data-model comparisons.

  1. Rapidity-even Dipolar Flow in Relativistic Heavy-Ion Collisions

    nucl-th 2026-07 conditional novelty 5.0 of 10

    GMC-suppressed rapidity-even dipolar flow correlations in AMPT and HIJING at 200 GeV show sensitivity to partonic transport and initial-state eccentricity correlations.

  2. Model Comparisons of Transverse Energy and Charged-Particle Multiplicity in A+A Collisions at Midrapidity from $\sqrt{s_{NN}}$ $=$ 7.7 to 200~GeV

    nucl-ex 2025-06 conditional novelty 4.0 of 10

    A broad model-data comparison shows that PYTHIA, AMPT, HIJING, and SMASH all fail to reproduce PHENIX transverse energy and multiplicity at low beam energies and in peripheral collisions.
