Hadronic observables in p plus p and d plus Au collisions at RHIC using CGC plus PYTHIA

摘要

The IP-Glasma model of CGC combined with the Lund model of PYTHIA provides a very successful description of hadron production from gluon dominated non-equilibrium matter in various small collision systems. This new CGC+PYTHIA framework, naturally reproduces several characteristic features of the hadronic observables such as the mass ordering of v(2)(p(T)) and p(T), often ascribed to collectivity driven by hydrodynamics at the LHC [1]. In this contribution we extend our work to provide a systematic comparison of particle spectra and multiplicity distributions in p+p and d+Au collisions at the RHIC.
