CMS track reconstruction performance and tracking developments during Run 3 / Bruschini, Davide (INFN, Pisa ; Pisa, Scuola Normale Superiore) /CMS Collaboration
The efficient and precise reconstruction of charged particle tracks is crucial for the overall performance of the CMS experiment. Prior to the beginning of the Run 3 at the LHC in 2022, the first layer of the Tracker Barrel Pixel subdetector was replaced in order to cope with the high pileup environment, and significant upgrades were made to the track reconstruction algorithms. [...]

CSC trigger primitive and segment efficiencies in 2024 /CMS Collaboration
This note contains Tag $\&$ Probe efficiency measurements for the CMS endcap muon CSCs from 2024 proton proton collisions data at 13.6 TeV. There is one plot for the tigger primitive efficiencies, and one for the reconstructed segment efficiencies..

Low transverse-momentum hadronic tau lepton reconstruction performance in the Run 3 Scouting dataset / The CMS Collaboration /CMS Collaboration
A technique for the reconstruction of low transverse momentum ($p_\text{T}$) hadronically decaying tau leptons in the CMS Run~3 Scouting datastream is presented. The addition of hadronic taus to the set of physics objects in Scouting opens possibilities for searches in new regions of phase space. [...]

Muon momentum calibration with proton-proton collisions at sqrt(s) = 13.6 TeV /CMS Collaboration
We present the results about the standard muon momentum scale and resolution measurements done on the proton-proton collision data collected during the 2022, and 2023 LHC proton-proton run at 13.6 TeV. Two different techniques have been applied to respectively study medium-p$_{T}$ and high-p$_{T}$ muons, as briefly described. [...]

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. [...]

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. [...]

Measurement of Higgs boson fiducial cross sections with the CMS detector and electromagnetic reconstruction with the high-granularity endcap calorimeter / Tarabini, Alessandro
This PhD thesis presents a comprehensive characterisation of the Higgs boson in the H → ZZ → 4ℓ decay channel, commonly known as the four-lepton channel, using proton-proton collisions at a centre-of-mass energy of 13 TeV recorded with the CMS experiment during the Run 2 of the CERN LHC [...]

Charming decays of the Higgs, Z, and W bosons: Development and deployment of a new calibration method for charm jet identification / Mondal, Spandan
This thesis presents searches for the Higgs boson, Z boson, and W boson decaying into charm quark(s) performed with proton-proton collision data at $\sqrt{s}$ = 13 TeV collected by the CMS experiment at the LHC, CERN, corresponding to an integrated luminosity of 138 fb$^{-1}$ and recorded between 20 [...]

Search for long-lived particles decaying into displaced dilepton vertices in proton-proton collisions at $\mathbf{\sqrt{s} = 13}$ TeV with the CMS detector / Fernandez Madrazo, Celia
Some of the most popular extensions of the Standard Model of Particle Physics contain long-lived particles, which can be framed in a wide variety of theories, covering different regions of the phase space [...]
