If the matter produced in ultrarelativistic heavy-ion collisions reaches thermal equilibrium, its subsequent evolution follows the laws of ideal fluid dynamics. We show that general predictions can be made on this basis alone, irrespective of the details of the hydrodynamical model. We derive several scaling rules for momentum spectra and anisotropic flow (in particular the elliptic flow, v2, and the hexadecupole flow, v4) of identified particles. Comparison with existing data is briefly discussed, and qualitative predictions are made for LHC.

  1. Nonlinear response of flow harmonics in Gubser flow with participant-reaction planes mismatch

    nucl-th 2026-04 unverdicted novelty 7.0

    Analytic nonlinear response coefficients for v2 and v4 in Gubser flow are derived, including a participant-plane angle factor that modifies strength and sign of the response.

  2. Enhanced hydrodynamic predictions for $v_{02}(p_T)$

    nucl-th 2026-07 conditional novelty 6.0

    Ideal hydrodynamics plus a v2-fitted correction predicts v02(pT): a high-pT decrease for charged hadrons, meson-baryon splitting, and a non-monotonic proton v02 in mid-central Pb+Pb.

  3. Explaining higher-order correlations between elliptic and triangular flow

    nucl-th 2025-11 unverdicted novelty 6.0

    Higher-order v2-v3 cumulants reduce to expressions fixed by the mean elliptic flow from nuclear overlap geometry.
