Proton-protoncollisions reached a peak instantaneous luminosity of2.1× 10$^{34}$ cm$^{-2}$s$^{-1}$, twice the initialdesign value, at √(s)=13 TeV. The CMS experimentrecords a subset of the collisions for further processing as part ofits online selection of data for physics analyses, using a two-leveltrigger system: the Level-1 trigger, implemented in custom-designedelectronics, and the high-level trigger, a streamlined version ofthe offline reconstruction software running on a large computerfarm. This paper presents the performance of the CMS high-leveltrigger system during LHC Run 2 for physics objects, such asleptons, jets, and missing transverse momentum, which meet the broadneeds of the CMS physics program and the challenge of the evolvingLHC and detector conditions. Sophisticated algorithms that wereoriginally used in offline reconstruction were deployedonline. Highlights include a machine-learning b tagging algorithmand a reconstruction algorithm for tau leptons that decayhadronically.}, keywords = {Large detector systems for particle and astroparticle physics (autogen) / Trigger concepts and systems (hardware and software) (autogen)}, cin = {CMS}, ddc = {610}, cid = {I:(DE-H253)CMS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF4-611) / DFG project G:(GEPRIS)390833306 - EXC 2121: Quantum Universe (390833306) / HIDSS-0002 - DASHH: Data Science in Hamburg - Helmholtz Graduate School for the Structure of Matter $(2019_IVF-HIDSS-0002)$ / GRK 2497 - GRK 2497: Physik der schwersten Teilchen am Large Hadron Collider (400140256)}, pid = {G:(DE-HGF)POF4-611 / G:(GEPRIS)390833306 / $G:(DE-HGF)2019_IVF-HIDSS-0002$ / G:(GEPRIS)400140256}, experiment = {EXP:(DE-H253)LHC-Exp-CMS-20150101}, typ = {PUB:(DE-HGF)16}, eprint = {2410.17038}, howpublished = {arXiv:2410.17038}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2410.17038;\%\%$}, UT = {WOS:001389636600001}, doi = {10.1088/1748-0221/19/11/P11021}, url = {https://bib-pubdb1.desy.de/record/619203}, }
