Full event interpretation with machine-learning-based particle-flow reconstruction in the CMS detector
The particle-flow (PF) algorithm constructs a global description of each particle collision by producing a comprehensive list of final-state particles, and is central to event reconstruction in the CMS experiment at the CERN LHC. [...]

Search for the pair production of long-lived supersymmetric partners of the tau lepton in proton-proton collisions at $ \sqrt{s}= $ 13 TeV
Gauge-mediated supersymmetry-breaking models provide a strong motivation to search for a supersymmetric partner of the tau lepton (stau) with a macroscopic lifetime. [...]

Strategy and performance of the CMS long-lived particle trigger program in proton-proton collisions at $ \sqrt{s}= $ 13.6 TeV
In the physics program of the CMS experiment during the CERN LHC Run 3, which started in 2022, the long-lived particle triggers have been improved and extended to expand the scope of the corresponding searches. [...]

Observation of $CP$ violation in $B^0 \to J/\psi \rho(770)^0$ decays
The time-dependent $C\!P$ asymmetry in $B^{0}\!\to{J\mskip-3mu/\mskip-2mu\psi}\rho(770)^0$ decays is measured using proton-proton collision data corresponding to an integrated luminosity of 6$fb^{-1}$ collected with the LHCb detector at a center-of-mass energy of 13 TeV during the years 2015–2018.
