“…It assumes that each nucleon participating in an inelastic collision is a wounded source. On the other hand, the wounded quark model [2], successfully applied to various colliding systems and at various energies [4][5][6][7][8][9][10][11][12], assumes that a heavy ion collision consists of independent quark-quark collisions and each constituent quark, undergoing inelastic collisions, is a wounded source. The number of wounded sources can assume different values [8] and, e.g., in Ref.…”

We note that wounded quark (diquark) properties can be naturally inferred from a differential proton-proton elastic cross section, as shown in Refs. [13][14][15][16]. 2 In the wounded nucleon model a nucleon from a deuteron populates particles independently on the number of collisions, whereas in the wounded quark model the number of particles depends on the number of wounded quarks, which clearly depends on the number of collisions.

“…The wounded quark model [2] is similar but constituent quark-quark collisions are considered. This model was studied recently in various contexts with rather interesting results [3][4][5][6][7][8][9][10][11][12][13]. In the wounded quark-diquark model [14], a nucleon is assumed to consist of a quark and a diquark.…”

Using the wounded nucleon, quark, and quark-diquark models, we extract the wounded source emission functions from the PHOBOS data for d+Au collisions at √ s N N = 200 GeV.We apply these models to compute charged particle multiplicity distributions as functions of pseudorapidity for p+p, p+Al, p+Au, d+Au, 3 He+Au, Cu+Cu, Cu+Au, Au+Au, and U+U collisions at the same energy and compare them with experimental data from the PHOBOS and PHENIX collaborations. In symmetric collisions of heavy nuclei, the obtained distributions differ among the tested models. On the other hand, in asymmetric collisions, all three models give essentially the same distributions. The wounded quark-diquark and quark models are in reasonable agreement with data for all the investigated systems.
