Qualification of Bump Bonding in CMS Inner Tracker Pixel Modules for the Phase-2 Upgrade
/ Assiouras, Panagiotis (INFN, Florence)
/CMS Collaboration
To fully exploit the increased luminosity of the HL-LHC, the CMS Inner Tracker is undergoing a major upgrade to withstand extreme radiation levels and data rates, while improving granularity and reducing material budget. The upgraded modules employ thin planar and 3D silicon pixel sensors, bump bonded to a new radiation-hard readout chip, the CROC, designed in 65 nm CMOS technology and powered via a serial scheme.

Current status of the CMS Inner Tracker upgrade for HL-LHC
/ Lorenzo Damenti of the CMS Collaboration
/CMS Collaboration
During the High Luminosity programme of the LHC collider (called HL-LHC), planned to start in 2030, the instantaneous luminosity will be increased from ∼2×1034cm−2s−1 to an unprecedented figure of about ∼7.5×1034cm−2s−1. This will allow the Compact Muon Solenoid (CMS) to collect up to ∼4000fb−1 of integrated luminosity over a decade.
In order to cope with the much higher pp-collisions rate, CMS will undergo an extensive improvement known as Phase 2 upgrade: in particular, the silicon tracker system will be entirely replaced to comply with the extremely challenging experimental conditions.
This contribution will review the main upgrades of the CMS Inner Tracker and will present the most relevant design and technological choices. [...]

CMS FIPs results and prospects
/ Alimena, Juliette (DESY)
/CMS Collaboration
The CMS Collaboration has recently written a report about the latest searches with the CMS Experiment in the dark sector. This report is a comprehensive review of dark sector searches with the CMS experiment at the LHC, using proton-proton and heavy ion collision data collected in Run 2, from 2016 to 2018, or, in some cases, from Run 1 (2011--2012) or Run 3 (2022).

Properties and rare production and decay processes of the Higgs boson in CMS
/ Bluj, Michal Jacek (NCBJ, Swierk)
/CMS Collaboration
This report summarises measurements of the Higgs boson properties performed with the CMS experiment at the CERN LHC. The measurements presented here base on data from pp collisions at center-of-mass energy of 7, 8 and 13 TeV collected up to year 2018 and corresponding to integrated luminosity of 5, 20 and 138 fb-1, respectively.

CMS Level-1 Data Scouting for High-Luminosity LHC
/ Sieder, Leah-louisa (CERN)
/CMS Collaboration
The CMS Experiment at the CERN Large Hadron Collider (LHC) relies on a Level-1 Trigger (L1T) system to process in real time all potential collisions, happening at a rate of 40 MHz, and select the most promising ones for data acquisition and further processing. The CMS upgrades for the up-coming high-luminosity LHC run will vastly improve the quality of the L1T event reconstruction, providing opportunities for a complementary Data Scouting approach where physics analysis is performed on a data stream containing all collisions but limited to L1T reconstruction. [...]
