Tracking performance using Tag and Probe with $ Z \rightarrow$ $\mu^{+}\mu^{-}$ in 2022 and 2023 /CMS Collaboration
The determination of the detector efficiency is a critical ingredient in any physics measurement. It can be in general estimated using simulations, but simulations need to be calibrated with data. [...]

Tau lepton identification in displaced topologies using machine learning at CMS /CMS Collaboration
Many extensions of the Standard Model can give rise to tau leptons produced with non-conventional signatures in the detector. Certain long-lived particles may decay into tau leptons displaced significantly from the primary proton-proton interaction vertex. [...]

Electron and photon reconstruction and identification performance at CMS in 2022 and 2023 /CMS Collaboration
This note presents the offline reconstruction and identification performance of electrons and photons at CMS using proton-proton collision data collected in 2022 and 2023 at a center of mass energy of 13.6 TeV. The corrections and scale factors derived and applied to collision data and simulation are also discussed..

Flower events in the GE1/1 detector /CMS Collaboration
This document illustrates few plots on the occurrence of high multiplity events in GE1/1 detectors. In these events a high number of strips register a fake hit. [...]

The history of GEM foil short circuit generation and healing (2021-2023) /CMS Collaboration
The GE1/1 station is made of triple GEM detectors and it was installed in CMS between 2019 and 2020. This document presents a study on the context of generation and healing of short circuits in GEM foils in GE1/1 detectors. [...]

Improved use of MTD time in vertex reconstruction /CMS Collaboration
An update on Mip Timing Detector (MTD) reconstruction performance is provided, focusing on the handling of uncertainties. The contribution to track time uncertainty coming from particle time of flight uncertainty $\sigma_{TOF}$ has been evaluated and compared to MTD uncertainty. [...]

Measurements of $p_{T}$ Dependent Bending Angles in the CMS GE1/1-ME1/1 System /CMS Collaboration
The Gas Electron Multiplier (GEM) subdetector system was designed for three stations in the endcap region. GEM GE1/1 chambers were installed in the first muon station during the second long shutdown (2019-2021) to achieve acceptable first level trigger rates for muons with reasonably low transverse momentum ($p_{T}$) thresholds. The performance of the standalone muon trigger is driven by the $p_{T}$-dependent bending angles measured between the GEM and Cathode Strip Chamber (CSC) detectors. [...]
