Production of the ϕ and Ω via recombination of jet parton showers in relativistic heavy ion collisions
Abstract
We study the production of the ϕ(1020) and Ω(1672) in heavy ion collisions at √(sNN) = 5.02 TeV by employing two complementary approaches. In the first approach, the production of the ϕ and Ω is discussed in the coalescence model. In the second approach, we developed a hybrid framework that combines the recombination of shower and thermal partons with remnant string fragmentation. Thermal partons in the quark-gluon plasma are modeled using a blast-wave parameterization, while the phase space information of medium-modified parton showers is generated from Q-PYTHIA, using unquenched jet partons obtained from HIJING initial inputs. We show that both approaches agree well with the experimental measurements, and demonstrate that this hybrid framework provides deeper insight into the underlying strangeness components in the production of ϕ and Ω in relativistic heavy-ion collisions.
