  "abstract": "We present a detailed chemical abundance analysis of seven red giant branch stars in the very metal-poor globular cluster NGC 4372 based on high-resolution UVES spectra. Our study aims to characterize the chemical evolution of NGC 4372 and investigate the presence of multiple populations. We derived abundances for 17 elements, including light, iron-peak, α, and heavy elements, using both equivalent width and spectral synthesis methods. We find a mean cluster metallicity of [Fe/H]=−2.36 ± 0.03 dex, with no evidence of an intrinsic iron spread. The cluster exhibits a typical α-enhancement of [α/Fe]= 0.33 ± 0.05 dex and a well-defined Na-O anticorrelation, confirming that NGC 4372 hosts at least two distinct stellar populations. Furthermore, the measured ratio of [Ba/Eu]=−0.47 ± 0.04 indicates that the synthesis of heavy elements was dominated by the r-process, consistent with other very metal-poor environments. We also identify a potential bimodal Mg–Al anticorrelation, which aligns with the patterns observed in globular clusters of similar masses and metallicities. These results reinforce the status of NGC 4372 as a cornerstone for understanding the early chemical enrichment of the Galactic halo.",
