Astrophysical observations provide compelling evidence for gravitationally interacting dark matter in the universe that cannot be explained by the standard model of particle physics. The extraordinary amount of data from the CERN LHC presents a unique opportunity to shed light on the nature of dark matter at unprecedented collision energies. This Report comprehensively reviews the most recent searches with the CMS experiment for particles and interactions belonging to a dark sector and for dark-sector mediators. Models with invisible massive particles are probed by searches for signatures of missing transverse momentum recoiling against visible standard model particles. Searches for mediators are also conducted via fully visible final states. The results of these searches are compared with those obtained from direct-detection experiments. Searches for alternative scenarios predicting more complex dark sectors with multiple new particles and new forces are also presented. Many of these models include long-lived particles, which could manifest themselves with striking unconventional signatures with relatively small amounts of background. Searches for such particles are discussed and their impact on dark-sector scenarios is evaluated. Many results and interpretations have been newly obtained for this Report.

A New Source of Millicharged Particles: Secondary Showers in the LHC Forward Absorber
Secondary cascades in the TAXN absorber produce a substantial millicharged particle flux that complements primary production and boosts FORMOSA signals by ~50% for m_χ below 0.1 GeV.

Collider Probes of Dark Energy Microphysics
Derivative couplings of a k-essence dark-energy scalar to a 2HDM+a pseudoscalar make the mediator’s invisible width and kinematics depend on the dark-energy sound speed c_s².

Light Antinuclei Coalescence: Femtoscopic Constraints via Neural-Flow Surrogates
A neural-flow emulator of the CECA femtoscopic source, fit to 49 ALICE pp correlation functions, reduces claimed uncertainties on antinuclei coalescence parameters B2 and B3 to a few percent and ~10% respectively.

Search for soft unclustered energy patterns in proton-proton collisions at $\sqrt{s}$ = 13 TeV using data scouting
No SUEP signal is observed in CMS scouting data; the search sets the most stringent limits to date on gluon-fusion production of heavy scalars decaying to SUEP-like final states.

Collider Probes of Dark Energy Microphysics
Collider observables of a pseudoscalar mediator resonance can become sensitive to the sound speed of dark energy fluctuations via modified propagation in a dark energy background.

Search for dark matter production in association with bottom quarks and a lepton pair in proton-proton collisions at $\sqrt{s}$ = 13 TeV
First dedicated CMS search for bb + dilepton + missing transverse momentum in the 2HDM+a model finds no signal and sets 95% CL cross-section limits of 10^-2 to 10^-3 pb for mH = 400-2000 GeV.

Search for the production of dark Higgs in the framework of Mono-Z$^{\prime}$ portal at the FCC-ee simulated electron-positron collisions at $\sqrt{s} = 240$ GeV
Expected FCC-ee dimuon+MET search could exclude dark Higgs masses 20-80 GeV at 95% CL for gl=0.003, gD=1.0 in the mono-Z' simplified model.

Relaxed constraints for dark matter with axial coupling to a dark photon
Axial coupling of Dirac dark matter to a kinetically-mixed dark photon suppresses the standard direct-detection signal and opens large allowed regions in the WIMP parameter space.

Search for emerging jets in $pp$ collisions at $\sqrt{s} = 13$ TeV with the ATLAS experiment
No excess of emerging-jet events appears in ATLAS Run 2 data, excluding pair-produced dark scalar mediators up to about 2 TeV for 20 GeV dark pions with 20 mm decay length.

GeV-scale thermal dark matter from dark photons: tightly constrained, yet allowed
In a dark-photon-mediated Dirac fermionic DM model, only narrow resonant regions with small dark-sector coupling allow the candidate to saturate the full relic density while evading current direct and indirect detecti...
