Forward-backward production ratios $R_\mathrm{FB}$ of $\Upsilon$ states are reported as functions of event activity variables, obtained from midrapidity as well as forward and backward rapidity regions. …”

The first jet identification algorithms were developed using classical methods, however since the beginning of LHC Run 2 the development of significantly more advanced methods, making use of machine learning techniques, led to substantial improvement in performance, and hence in the physics reach.…”
