We show that centrality dependence of charged particle pseudorapidity density at midrapidity in Au+Au collisions at RHIC is well described as proportional to We show that centrality dependence of charged particle pseudorapidity density at midrapidity in Au+Au collisions at RHIC is well described as proportional to the number of participating constituent quarks. In this approach there is no need for an additional contribution from hard processes usually considered in the models based on the number of the nucleon participants.

  1. Saturation effects in exclusive vector meson production in DIS

    hep-ph 2025-11 conditional novelty 6.0 of 10

    A dense-limit CGC hotspot calculation shows saturation mildly suppresses exclusive vector meson cross sections in ep, with suppression growing at higher color-charge density.

  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 of 10

    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. Constraining hot and cold nuclear matter properties from heavy-ion collisions and deep-inelastic scattering

    nucl-th 2025-04 unverdicted novelty 5.0 of 10

    Global analysis of HERA DIS and ALICE Pb+Pb data using saturation initial-state model determines early-time non-equilibrium η/s of QGP.

  4. Multiplicity fluctuations in the Glauber Monte Carlo approach

    hep-ph 2019-09 conditional novelty 5.0 of 10

    Wounded quark sources with shadowing in a Glauber Monte Carlo model reproduce the centrality dependence of multiplicity fluctuations measured by NA49 in Pb+Pb collisions for 80 to 200 projectile participants.
