CSC calibration constants and validation using the 2022 calibration runs data /CMS Collaboration
CSC cathode calibration data (pedestals, gains, crosstalk, and noise matrix) were updated using calibration runs taken in 2022. This note describes what they are, how they were obtained, their validation, and their use as conditions data in simulation and in reconstruction of real data..

Use of HGCAL and MTD timing information in TICL reconstruction /CMS Collaboration
The High Granularity Calorimeter (HGCAL), planned for Phase 2 of the LHC, provides a measurement of the time of arrival (TOA) for all individual energy deposits above a few minimum ionizing particle (MIP)-equivalent. The precision of the TOA for reconstructed showers from high $p_T$ particles is expected to be limited by a floor precision of about 20 ps. [...]

Displaced Vertex Track Trigger for the CMS Phase-2 Level-1 Trigger Upgrade /CMS Collaboration
As part of the CMS Phase-2 upgrade, track information from the outer tracker will be available at the Level-1 trigger and with this comes the expanded opportunity to trigger on physics objects such as long-lived particles (LLPs). Presented here is a feasibility study in calculating displaced vertex information using an extended version of the Level-1 tracking that identifies displaced tracks. [...]

CPU performance evolution of Full simulations using Phase-2 geometry from Run-3 \mbox{CMSSW 11\_0\_4 to 14\_0\_1} /CMS Collaboration
The following plot shows the historical evolution of the Phase-2 CMS detector Simulation CPU time performance. For Phase-2 simulation the same Physics List FTFP\_BERT\_EMM (FTFP (Fritiof)/BERT (Bertini Cascade) model for hadronic processes, EMM for electromagnetic processes) as the one developed for Run-3 is used.
