Abstract
These proceedings present a set of PHENIX highlight results using recent high-luminosity data sets for p+p, p (d, 3He)+A, and A+A(B) collisions at RHIC top energies with a focus on: (1) light-flavor particle productions; (2) hard-probes such as jet-like correlations, direct photon, and heavy-quark productions; and (3) azimuthal anisotropy in small collision systems.

We discuss the following recent highlight results from such an effort: (i) π0, η, and φ meson productions; (ii) direct γ-hadron correlations and single direct photon production; (iii) inclusive J/ψ and bbpair productions; and (iv) azimuthal anisotropy in small collision systems
The new measurement of direct photon fraction Rγ with the external conversion method reconfirms the previous measurements with different methods over the wide pT range, significantly reducing the systematic uncertainties at high pT
Summary
The focus of the PHENIX heavy-ion program has been complete analyses of recent high-luminosity data sets for p+p, p (d, 3 He)+Au(Al), as well as Au(Cu)+Au and U+U collisions at RHIC top energies In these proceedings, we discuss the following recent highlight results from such an effort: (i) π0 , η, and φ meson productions;. In both collisions, RAA of various hadrons follows one universal curve at high-pT probably due to flavor-independent energy loss in the medium. In p+Al collisions, PYTHIA and AMPT without coalescence effects better describe the data This implies that the QGP medium does not form in p+Al collisions. This observation can be quantitatively reproduced by the CoLBT_Hydro model calculation [3]
