16. Hadron–strangeness correlations as a function of multiplicity in the pp collisions with ALICE

Lucia Anna Tarasovicova (Pavol Jozef Safarik University (SK))

Measurements in pp and p-Pb collisions have revealed that these small collision systems exhibit several features traditionally attributed to heavy-ion collisions, including the smooth increase of the strange hadron yields with the collision multiplicity (strangeness enhancement). However, the microscopic origin of this phenomenon in small systems remains an open question. In particular, the...

21. Probing jet quenching in OO collisions with ALICE

Filip Krizek (Czech Academy of Sciences (CZ))

The ALICE experiment investigates the properties of the quark-gluon plasma (QGP) created in ultrarelativistic heavy-ion collisions. Two of the most prominent signatures of QGP formation are the collective hydrodynamic expansion of the produced medium and the energy loss of high-energy partons traversing the medium, known as jet quenching. Measurements in small collision systems, such as p-Pb,...

8. Study of Z-tagged jet substructure in PbPb and pp collisions at 5.36 TeV with the ATLAS experiment

Emil Lelak (Charles University (CZ))

This contribution presents the status of an ongoing ATLAS analysis of jet substructure in Z+jet events in heavy-ion and proton-proton collisions at the energy of 5.36 TeV. The study utilizes Z bosons reconstructed through their dilepton decay channels and examines jet substructure observables to investigate modifications of the parton shower in the quark-gluon plasma – extremely hot and dense...

33. Jet nuclear modification measurements with the ATLAS detector

Mr Franciszek Pauwels (Charles University IPNP)

10/09/2026, 17:42

Measurements of jet production in nuclear collisions provide important constraints on parton energy loss and the properties of the quark–gluon plasma. This contribution presents recent ATLAS studies of jet nuclear modification using LHC collision data. Jet yields are compared with suitable proton–proton reference measurement and studied as functions of jet transverse momentum, collision...
