NoOffer DescriptionIn high-energy heavy-ion collisions at CERN, up to 10,000 particles are produced, including light (anti)nuclei.
Using advanced particle-identification detectors, ALICE has measured nuclear states with A < 5 across pp, p–Pb, and Pb–Pb collisions.
No model fully describes the data quantitatively; common approaches include the statistical-hadronization and coalescence models.
Recent measurements of higher-order moments of antideuteron and antiproton numbers offer valuable insights to distinguish nucleosynthesis models, being sensitive to baryon-number conservation while less affected by systematic effects.The project aims to measure yield fluctuations of light (anti)nuclei using 2023/24 data with unprecedented luminosity, allowing precise measurements of rare states like anti-3 He.
Studying the Pearson correlation between anti-3He and antiproton counts will refine coalescence modeling, offering tighter constraints on (anti)nuclei formation and nucleon emission processes in collisions.Eligibility of fellowsCountry/ies of residence: AllNationality/ies: #J-18808-Ljbffr
