Description
Light nuclei are loosely bound objects with a few MeV binding energies. The systematic measurement of light nuclei production in heavy-ion collisions across a wide energy range is a valuable tool to probe the QCD phase structure and gain insight into the underlying production mechanism. In 2018, RHIC started the second phase of the beam energy scan program (BES-II). The STAR Fixed Target (FXT) program was proposed to achieve lower center-of-mass energies and higher baryon density regions. Up to now, the STAR experiment has recorded high statistics data at $\sqrt{s_{\mathrm{NN}}}$ = 3 - 13.7 GeV in Au+Au collisions.
In this poster, we will present the proton and light nuclei production in Au+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 3 GeV (FXT) recorded by the STAR experiment. The analysis will include results from center to peripheral collisions, and span from mid-rapidity to target rapidity. The transverse momentum ($p_{T}$) spectra, coalescence parameters ($B_{A}$), particle ratios, and compound yield ratios will be shown and compared with other experiment groups for a wide range of energies.
