Space-time development of in-medium hadronization: Scenario for leading hadrons
2017-12-05, GUIOT , BENJAMIN CHARLES, Kopeliovich, B., L. Bravina, Y. Foka, S. Kabana
Lepton deep inelastic scattering off nuclei at medium energies gives the opportunity to study the space-time development of hadronization. Indeed, for these kinematics, the production length is comparable to the nuclear size. Based on the Berger model [1] and dipole phenomenology, we built a model for vacuum and in-medium hadronization. The model, which includes vacuum energy loss, induced energy loss and nuclear absorption in a parameter-free way successfully describes Hermes data [2, 3]. In a future publication, Fermi motion will be taken into account and the model will be applied to CLAS Eg2 data, at Jefferson laboratory.
System size dependence of particle production in EPOS
2018-09-18, Werner, K., GUIOT , BENJAMIN CHARLES, Karpenko, Iu, Pierog, T., Sophys, G., Stefaniak, M.
The aim of this paper is to understand particle production for different collision systems, namely proton-proton (pp), proton-nucleus (pA), and nucleus-nucleus (AA) scattering at the LHC. We will investigate in particular particle yields and ratios versus multiplicity, using the same multiplicity definition for the three different systems, in order to analyse in a compact way the evolution of particle production with the system size and the origin of a very different system size dependence of the different particles.
