  "abstract": "The recent measurements of event-by-event correlations between the antideuteron and antiproton numbers in Pb$-$Pb collisions at the LHC deviate from the statistical hadronization model parameterizations that describe the yields and fluctuations of light-flavored hadrons. This discrepancy may stem from nucleosynthesis processes involved in the formation of composite states like antideuterons. In this letter, we present the first measurement of the antideuteron$-$net-$Λ$ number correlation obtained in Pb$-$Pb collisions with the ALICE detector. This quantity is mostly sensitive to the quantum-number correlations induced by the hadronization process, as $Λ$ hyperons are not constituents of antideuterons. Both the antideuteron$-$net-$Λ$ number correlation and the normalized second-order cumulant of the net-$Λ$ number are well described by the statistical hadronization model implemented in Thermal-FIST. This establishes strong evidence that the antideuteron$-$antiproton correlation is driven by the nucleosynthesis processes, while the correlation between antideuterons and non-nucleonic hadrons is primarily sensitive to the hadronization mechanism.",
