Summary: | PHENIX presented several new results at Quark Matter 2019 in 7 parallel talks and 7 posters. These proceedings highlight a sampling of the measurements presented during the conference. PHENIX results on flow in small systems, published in Nature Physics, indicate that the flow in small systems is driven by the initial state geometry. Additional measurements exploring QGP effects in small systems have also been explored. Two-particle correlations in d+Au and 3He+Au suggest potential modification compared to those in p+p collisions. PHENIX has also measured J/Ψ in the forward and backward rapidity regions in d+Au and 3He+Au collisions. Thermal photon measurements are also consistent with QGP formation in small systems. A new measurement of thermal photons using the Au+Au data set collected by PHENIX in 2014 verifies the scaling relationship previously observed for thermal photons. New results for a variety of hadron species with increasing precsion are now available and provide both insight into hadronization as well as crucial information for energy loss models that use RAA to tune their parameters. Jet modification is also studied via a new observable extracted from π0-hadron correlations in Au+Au collisions. |
