We argue that the emission of hadrons with transverse momentum up to about 5 GeV/c in central relativistic heavy ion collisions is dominated by recombination, rather than fragmentation of partons. This mechanism provides a natural explanation for the observed constant baryon-to-meson ratio of about one and the apparent lack of a nuclear suppression of the baryon yield in this momentum range. Fragmentation becomes dominant at higher transverse momentum, but the transition point is delayed by the energy loss of fast partons in dense matter.

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

    nucl-th 2026-07 conditional novelty 6.0 of 10

    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.

  2. How AMPT generates large elliptic flow with small cross sections

    nucl-th 2019-06 unverdicted novelty 6.0 of 10

    AMPT generates high elliptic flow with few-millibarn cross sections due to specific features in initial conditions, interactions, and partonic dynamics, identified via comparisons with the MPC model.

  3. Probing medium response via strangeness enhancement around quenched jets

    nucl-th 2024-12 conditional novelty 4.0 of 10

    In the AMPT model, jet-induced medium excitation enhances the strange-to-non-strange hadron ratio around quenched jets in Pb+Pb collisions, increasing with centrality and radial distance.
