Quarkonia are excellent probes for studying the interactive properties of quark-gluon plasma formed in relativistic heavy-ion collisions. To correctly interpret the observed suppression of quarkonium production in $\text{Au}+\text{Au}$ collisions at $\sqrt{s_{\text{NN}}}$ = 200 GeV, the cold nuclear matter (CNM) effects in $p+\text{Au}$ collisions are quantified by the nuclear modification...
Ultra-peripheral Ru+Ru and Zr+Zr collisions at $\sqrt{s_{\mathrm{NN}}}=200~\mathrm{GeV}$ at RHIC provide a controlled setting for investigating nuclear-structure effects in the photonuclear production of forward neutrons. Although the two isobars have the same mass number, they differ in proton number and photonuclear response, making their neutron-tagged Coulomb-dissociation cross-section...
