Efficiencies of New Low-pT Lepton+HT+b-tag Triggers for Run-3
/CMS Collaboration
This note presents the performance of new lepton + $H_{T}$ + b-tag cross triggers introduced in 2024 in order to improve the trigger acceptance for $HH \rightarrow b\bar{b}WW^{*}$ events with low-$p_{T}$ leptons (electrons or muons)..

Calibration of the top and W jet tagging efficiency in 13 TeV data collected by the CMS experiment in 2016--2018
/CMS Collaboration
This note presents a collection of efficiency correction factors, to be applied to simulation, for jet tagging algorithms designed for the identification of hadronically decaying top quarks or W bosons. These scale factors are calculated from and valid for the proton--proton collision data set at $\sqrt{s} = 13$\,TeV of the 2016, 2017, and 2018 data-taking eras of the CMS experiment, using the legacy data reconstruction and calibration, corresponding to a total integrated luminosity of 138\,$\text{fb}^{-1}$.

Performance of the ParticleNet b and bb-tagging algorithms in the CMS High-Level Trigger in Run 3
/CMS Collaboration
Dedicated ParticleNet AK4 b-tagging and AK8 bb-tagging algorithms, based on graph neural networks (GNN), for the jets reconstructed at the High-Level Trigger (HLT) were trained for the very first time in 2022 using simulated events. New triggers were developed based on these algorithms that have been integrated into the CMS HLT menu since the start of Run 3 data-taking. [...]

Bunch crossing identification studies for the CMS muon barrel local trigger
The CMS barrel muon chambers individually produce trigger primitives (TP) to be fed in the Barrel Muon Track Finder (BMTF) for Level 1 triggering. These TPs are mainly built up out of the space (position, direction) and time information provided by the Drift Tubes (DT). [...]

Pixel Detector Performance in Run 3 (December 2024)
/CMS Collaboration
The Large Hadron Collider (LHC) continued delivering proton-proton collisions in 2024 as part of the LHC Run 3 that started in 2022. The collisions are produced at the centre-of-mass energy of 13.6 TeV. [...]
