Title:  Recent results from light-ion collisions by ALICE

Speaker: Professor Anthony Timmins (University of Houston)

Abstract: 

During the twenty years since the discovery of the perfect fluid at RHIC with gold-gold collisions, one key question has persisted: how small can this fluid be? The recent light-ion collisions at the LHC offer a unique opportunity to address this by bridging the system-size gap between proton–nucleus and heavy-ion collisions. While proton–proton and proton–nucleus systems have exhibited features reminiscent of quark–gluon plasma formation, such as strangeness enhancement and collective flow, hydrodynamic interpretations and jet-quenching searches remain inconclusive. I will present the first ALICE results from light-ion collisions, with an emphasis on collective phenomena and high-momentum probes. Comparisons with measurements from other LHC experiments will be discussed to assess whether a global picture is emerging. Together, these results provide new insight into the possibility that droplets of quark–gluon plasma are created in oxygen–oxygen and neon–neon collisions.
