Jet measurements in small systems relevant for in-medium modifications / Radl, Attila Jozsef (Budapest, RMKI) /ALICE, ATLAS and CMS Collaborations
Ultrarelativistic heavy-ion collisions provide insights into the early stages of the expanding universe. The quark-gluon plasma (QGP) is a unique state of matter formed in such high-energy interactions. [...]

Studying the interaction between charm and light-flavor mesons / Acharya, Shreyasi (Clermont-Ferrand U.) ; Adamova, Dagmar (Rez, Nucl. Phys. Inst.) ; Aglieri Rinella, Gianluca (CERN) ; Aglietta, Luca (Turin U. ; INFN, Turin) ; Agnello, Michelangelo (Turin Polytechnic) ; Agrawal, Neelima (Bologna U. ; INFN, Bologna) ; Ahammed, Zubayer (Calcutta, VECC) ; Ahmad, Shakeel (Aligarh Muslim U.) ; Ahn, Sang Un (KISTI, Daejeon) ; Ahuja, Ishaan (Kosice U.) et al.
The two-particle momentum correlation functions between charm mesons ($\mathrm{D^{*\pm}}$ and $\mathrm{D}^\pm$) and charged light-flavor mesons ($\pi^{\pm}$ and K$^{\pm}$) in all charge-combinations are measured for the first time by the ALICE Collaboration in high-multiplicity proton-proton collisions at a center-of-mass energy of $\sqrt{s} =13$ TeV. For $\mathrm{DK}$ and $\mathrm{D^*}\mathrm{K}$ pairs, the experimental results are in agreement with theoretical predictions of the residual strong interaction based on quantum chromodynamics calculations on the lattice and chiral effective field theory.

Insights on strange quark hadronization in small collision system with ALICE: multiple strange hadrons and $\Sigma^{\pm}$ baryons / Pucillo, Sara
Among the most iconic results of Run-1 and Run-2 of the LHC is the observation of enhanced production of (multi-)strange to non-strange particles, gradually rising from low-multiplicity to high-multiplicity pp or p--Pb collisions and reaching values close to those measured in peripheral Pb--Pb collisions.
