Dark-Sector Search via Pion-Produced η and η′ Mesons Decaying Invisibly in the NA64h Detector / NA64 Collaboration
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar η and η′ mesons in the NA64h experiment at the CERN SPS. Our novel technique uses the charge-exchange reaction of 50 GeV π- on nuclei of an active target as the source of neutral mesons. [...]

Performance of the CMS high-level trigger during LHC Run 2 / CMS Collaboration
The CERN LHC provided proton and heavy ion collisions during its Run 2 operation period from 2015 to 2018. Proton-proton collisions reached a peak instantaneous luminosity of 2.1 $ \times $ 10$^{34}$ cm$^{-2}$s$^{-1} $, twice the initial design value, at $ \sqrt{s}= $ 13 TeV. [...]

Shedding light on Dark Sectors with high-energy muons at the NA64 experiment at the CERN SPS / Andreev, Yu.M. (Unlisted) ; Banerjee, D. (CERN) ; Banto Oberhauser, B. (Zurich, ETH) ; Bernhard, J. (CERN) ; Bisio, P. (Kobe U. ; INFN, Genoa) ; Charitonidis, N. (CERN) ; Crivelli, P. (Zurich, ETH) ; Depero, E. (Zurich, ETH) ; Dermenev, A.V. (Unlisted) ; Donskov, S.V. (Unlisted) et al. /NA64
A search for Dark Sectors is performed using the unique M2 beam line at the CERN Super Proton Synchrotron. New particles ($X$) could be produced in the bremsstrahlung-like reaction of high energy 160 GeV muons impinging on an active target, $\mu N\rightarrow\mu NX$, followed by their decays, $X\rightarrow\text{invisible}$. [...]

Measurement of the $B^0_\mathrm{s}\to J/\psi K^0_\mathrm{S}$ effective lifetime from proton-proton collisions at $\sqrt{s} = 13$ TeV / CMS Collaboration
The effective lifetime of the $ \mathrm{B}_{s}^{0} $ meson in the decay $ \mathrm{B}_{s}^{0} \to \mathrm{J}/\psi\mathrm{K^0_S} $ is measured using data collected during 2016-2018 with the CMS detector in $ \sqrt{s}= $ 13 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 140 fb$ ^{-1} $. The effective lifetime is determined by performing a two-dimensional unbinned maximum likelihood fit to the $ \mathrm{B}_{s}^{0} $ meson invariant mass and proper decay time distributions. [...]

Measurement of boosted Higgs bosons produced via vector boson fusion or gluon fusion in the $ \mathrm{H}\to\mathrm{b}\overline{\mathrm{b}} $ decay mode using LHC proton-proton collision data at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A measurement is performed of Higgs bosons produced with high transverse momentum ($ p_{\mathrm{T}} $) via vector boson or gluon fusion in proton-proton collisions. The result is based on a data set with a center-of-mass energy of 13 TeV collected in 2016-2018 with the CMS detector at the LHC and corresponds to an integrated luminosity of 138 fb$ ^{-1} $. [...]

Observation of double $ \mathrm{J}/\psi $ meson production in pPb collisions at $ \sqrt{\smash[b]{s_{_{\mathrm{NN}}}}} $ = 8.16 TeV / CMS Collaboration
The first observation of the concurrent production of two $ \mathrm{J}/\psi $ mesons in proton-nucleus collisions is presented. The analysis is based on a proton-lead (pPb) data sample recorded at a nucleon-nucleon center-of-mass energy of 8.16 TeV by the CMS experiment at the CERN LHC and corresponding to an integrated luminosity of 174.6 nb$^{-1}$.

Combination of measurements of the top quark mass from data collected by the ATLAS and CMS experiments at $\sqrt{s}=7$ and 8 TeV / ATLAS Collaboration
A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 20$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. [...]

Search for $CP$ violation in D$^0$$\to$ K$^0_\mathrm{S}$K$^0_\mathrm{S}$ decays in proton-proton collisions at $\sqrt{s}$ = 13 TeV / CMS Collaboration
A search is reported for charge-parity CP violation in $ \mathrm{D^0}\to\mathrm{K^0_S}\mathrm{K^0_S} $ decays, using data collected in proton-proton collisions at $ \sqrt{s} = $ 13 TeV recorded by the CMS experiment in 2018. The analysis uses a dedicated data set that corresponds to an integrated luminosity of 41.6 fb$ ^{-1} $, which consists of about 10 billion events containing a pair of b hadrons, nearly all of which decay to charm hadrons.
