The ϕ(1020)0mesons produced by asymmetric Cu–Aucollisions at sNN=200GeVin the pseudorapidity region of |η|<0.35is studied in relation to the transverse momentum (pT). The nuclear modification factor (RAB) is also calculated for ϕ(1020)0mesons. To validate the model’s predictions, the simulations are compared to the experimental data from PHENIX using the PYTHIA8 and tuned to color reconnection mode. A systematically close relationship exists between PYTHIA8 predictions and the PHENIX data. PYTHIA CR1 mode predictions do not agree well with PHENIX experimental data. In addition to the RABpredictions, we investigated the ratio between the production of ϕ(1020)0mesons to K∗(892)0mesons and Λbaryons in Cu–Aucollisions at sNN=200GeV. A comparison of the ϕ(1020)0mesons yield produced by symmetric Au–Auand Cu–Cucollisions at sNN=200GeVare conducted using PYTHIA8 for comparison against asymmetric Cu–Aucollisions. In this study, we also fit thermodynamically consistent Tsallis distribution functions for ϕ(1020)0mesons onto experimental RHIC (PHENIX) pTspectra obtained from Cu–Aucollisions at sNN=200GeVenergy.
