Jets are powerful probes used to improve our understanding of fundamental particle physics, including recent progress aiming to identify highly-boosted particles decaying hadronically. In this talk, we will discuss the Lund jet plane, a representation of the phase space inside jets inspired by Lund diagrams used in resummations and Monte Carlo event generators. We will review applications of the Lund jet plane, focusing primarily the measurements and theoretical calculations of the primary Lund jet plane density.

Cristian Baldenegro obtained his PhD at the University of Kansas and is currently a postdoctoral researcher at the Laboratoire Leprince-Ringuet with the ERC project "QCDHighDensityCMS". His research focus revolves around jet physics and small-x physics in proton-proton and lead-lead collisions with the CMS experiment. He is convener of the forward & ultraperipheral collisions group of CMS.

Gregory Soyez is a theoretical physicist working on perturbative QCD. His main topics of interest include jet physics and parton showers. He is working at the IPhT (CEA Saclay) since 2010 and currently visiting CERN until the end of August 2023.
