“…The study of the Quark-Gluon Plasma created in ultrarelativistic heavy-ion collisions at the CERN-LHC is complemented by reference measurements in proton-lead (p--Pb) and proton-proton (pp) collisions, where the effects of multiple-parton interactions and hadronization beyond independent string fragmentation can be investigated. …”

“…The suppression of the ${\mathrm{J}/\psi}$ yield shows a dependence on $z$, indicating that the interaction of the ${\mathrm{J}/\psi}$ with the quark-gluon plasma formed in heavy-ion collisions depends on the fragmentation pattern of the jet that gives rise to the ${\mathrm{J}/\psi}$ meson.…”

“…Particular emphasis is placed on the latest measurements of $H \rightarrow b\bar{b}$ via associated vector boson production ($VH$) from ATLAS, an inclusive search for $H \rightarrow b\bar{b}$ via gluon fusion ($ggF$) plus jet production from CMS, and a CP-invariance test using $H \rightarrow \tau\tau$ via vector-boson fusion production (VBF).…”

“…Jet substructure provides information about quantum chromodynamics (QCD) and plays an important role in the study of the evolution of the quark-gluon plasma. The ALICE experiment is uniquely suited to provide insight into the smallest splitting angles due to high efficiency in the reconstruction of charged particles. …”

“…The hard jet structure is sensitive to the virtuality evolution of a parton in the medium, as well as the role of (de)coherent gluon emitters. Modifications of shared momentum fraction and jet mass over a wide range of jet transverse momentum and various collision centrality selections are reported and compared to predictions from event generators and analytical calculations.…”

“…In particular, coherent charmonium mesons are promising probes of nuclear shadowing due to their sensitivity to the nuclear parton distribution function of gluons. In this presentation, we report the measurements of the differential coherent cross section productions as a function of rapidity for J/ψ meson in ultra-peripheral PbPb collisions at a nucleon-nucleon centre-of-mass energy of 5.02TeV. …”

“…These include measurements of vn-[pT] correlations in Xe+Xe and Pb+Pb, which carry important information about the initial-state geometry of the Quark-Gluon Plasma and can potentially shed light on any quadrupole deformation in the Xe nucleus; measurements of flow decorrelations differential in rapidity, which probe the longitudinal structure of the colliding system; and measurements of the sensitivity of collective behavior in pp collisions to the presence of jets, which seek to distinguish the role that semi-hard processes play in the origin of these phenomena in small systems. …”

“…Measurements of heavy-flavor hadron production in heavy-ion collisions provide a powerful tool to study both initial-state effects on heavy-quark production and final-state interactions between heavy-quarks and the quark-gluon plasma. These measurements are performed with the ATLAS detector at the LHC and capitalize on the large statistics of the Run 2 Pb+Pb dataset. …”

“…Recent studies have linked polarization to the process of hadronization, which describes how particular hadrons are formed from scattered quarks and gluons. The high energy of the LHC and the coverage and precision measurement possibilities from LHCb forward geometry are ideal for studying hyperon polarization as a function of both $p_T$ and $x_F$. …”
