Highlights from the STAR experiment

Understand

The STAR experiment at the Relativistic Heavy Ion Collider (RHIC) studies properties and phase transitions of nuclear matter in various nucleus-nucleus collisions at center-of-mass energies per nucleon collision $\sqrt{s_{NN}}=7.7$-200 GeV.

• With a fixed target made of gold foils installed inside the beam pipe, STAR also starts to explore high baryon density regime ($\mu_B\approx420$-720 MeV) at $\sqrt{s_{NN}}=3.0$-7.7 GeV.
• A few selected results reported by the STAR collaboration at the Quark Matter 2018 (QM2018) conference are described in these proceedings.
