“…In lepton colliders, it gives a precise determination of the line-shape production of the J/ψ, the Z and the Higgs bosons, while in QCD it allows a realistic description of quark and gluon jets, of the transverse momentum distribution of W, Z and H produced in hadron collisions, and other related quantities. …”

“…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. …”

“…The DeepTau identification algorithm is used to identify hadronically decaying tau leptons from quark and gluon induced jets, electrons, and muons. Compared to previously used MVA identification algorithms, the use of deep-learning techniques brought a noticeable improvement in the tau identification and rejection of contaminating sources. …”

“…In particular, by tagging the final state jet as quark-initiated we have been able to enhance the initial-state gluon contribution. I discuss new resummed theoretical predictions for the transverse momentum distributions of events selected by the tagger which would be potentially interesting to probe the gluonic degrees of freedom of the colliding protons.…”

“…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 $x_F$ . …”
