The commissioning of the Upstream Tracker for the LHCb upgrade / Abellan Beteta, C (Zurich U.) /LHCb UT Collaboration
The LHCb detector has undergone a major upgrade that will enable the experiment to acquire data with an all-software trigger, made possible by front-end readout in real-time and the capabilities of performing the data selection algorithm while the data are acquired. To achieve this goal, almost all detector subsystems have been replaced by new designs mandated by the processing speed requirements. [...]

40 MHz readout of CMS silicon modules in a high intensity beam / Monk, David (Northwestern U.) /CMS Tracker Group-MUonE Collaboration
In order to maintain its outstanding performance under the challenging conditions brought by the high-luminosity LHC, the CMS collaboration is preparing the production of a new outer tracker detector. The upgraded detector modules will feature two silicon sensors and the ability of reading out correlated clusters, or stubs, compatible with high transverse momentum particles at the full 40 MHz collision rate. [...]

Performance of boosted $b\bar{b}$ jet tagging at $\sqrt{s}$ = 13.6 TeV with Run 3 CMS data /CMS Collaboration
Decay products of particles produced with high Lorentz-boosts are highly collimated and, in case of a hadronic decay, they can be reconstructed as one large massive jets. Therefore, the identification of the particle(s) initiating the jet plays a crucial role in distinguishing between boosted resonances and QCD multijet background. [...]
