Measurements of differential Higgs boson production cross sections in the leptonic WW decay mode at $\sqrt{s} = 13~\mathrm{TeV}$
/CMS Collaboration
Measurements of differential production cross sections of the Higgs boson in pp collisions at $\sqrt{s} = 13~\mathrm{TeV}$ are performed using events where the Higgs boson decays into a pair of W bosons which subsequently decay into an electron, a muon, and a pair of neutrinos. The analysis is based on data collected by the CMS detector at the LHC in 2016, 2017, and 2018, and corresponds to an integrated luminosity of $137~\mathrm{fb}^{-1}$. [...]

A measurement of the mass of the Higgs boson in the diphoton decay channel is presented. This analysis is based on 35.9 fb$^{-1}$ of proton-proton collision data collected in 2016 with the CMS detector at a center-of-mass energy of 13 TeV. [...]

A deep neural network for simultaneous estimation of b quark energy and resolution
/CMS Collaboration
We describe a method to obtain point and dispersion estimates for the energy of jets arising from bottom quarks (b jets) in proton-proton (pp) collisions at the CERN LHC. The algorithm is trained using a large simulated sample of b jets produced in pp collisions recorded at an energy of $\sqrt{s}=13~\mathrm{TeV}$ and validated on data recorded by the CMS detector in 2017 with an integrated luminosity of $41~\mathrm{fb}^{-1}$.

Template measurement of the top quark forward-backward asymmetry and anomalous chromoelectric and chromomagnetic moments in the semileptonic channel at sqrt(s)=13 TeV
/CMS Collaboration
The linearized parton-level top quark forward-backward asymmetry $A^{(1)}_{\mathrm{FB}}$ and anomalous chromoelectric ($d$) and chromomagnetic ($\mu$) moments are measured in $35.9~\text{fb}^{-1}$ of LHC proton-proton collision data collected with the CMS detector in 2016 at a center-of-mass energy $13~\text{TeV}$. Candidate top quark/antiquark pair events decaying to lepton (muon or electron) plus jets final states with ``resolved" (low energy) and ``boosted" (high energy) topologies are selected and reconstructed using a kinematic fit of the decay products to top quark pair hypotheses.

Search for a narrow resonance decaying to a pair of muons in proton-proton collisions at 13 TeV
/CMS Collaboration
A search is presented for a narrow resonance decaying to a pair of muons using 13 TeV proton-proton collision data recorded by the CMS experiment at the CERN LHC. The search in the $45-75$ and $110-200$ GeV resonance mass ranges uses fully reconstructed event data, corresponding to an integrated luminosity of 137 fb$^{-1}$. [...]

Observation of the $\Lambda_{\mathrm{b}} \to \mathrm{J}/\psi \Lambda \phi$ decay in proton-proton collisions at $\sqrt{s}=$ 13 TeV
/CMS Collaboration
We report a first observation of the $\Lambda_{\mathrm{b}} \to \mathrm{J}/\psi \Lambda \phi$ decay using proton-proton collision data collected at $\sqrt{s}$= 13 TeV by the CMS experiment at the LHC, and corresponding to an integrated luminosity of 60 $\mathrm{fb}^{-1}$. The ratio of the branching fractions ${\cal B}(\Lambda_{\mathrm{b}} \to \mathrm{J}/\psi \Lambda \phi)/{\cal B}(\Lambda_{\mathrm{b}}\to \psi\mathrm{(2S)} \Lambda)$ is measured to be $(8.26\pm0.90~\mathrm{(stat)} \pm0.68~\mathrm{(syst)}\pm0.11({\cal B}))\times 10^{-2}$, where the first uncertainty is statistical, the second is systematic, and the third is due to the uncertainties in the world-average branching fractions..

Measurement of properties of Bs0 to mu+mu- decays and search for
B0 to mu+mu- with the CMS experiment
/CMS Collaboration
Results are reported for the ${\rm B_s^0}\to\mu^+\mu^-$ branching fraction and effective lifetime and from a search for the decay ${\rm B^0}\to\mu^+\mu^-$. The analysis uses a data sample of proton-proton collisions accumulated by the CMS experiment in 2011, 2012, and 2016, with center-of-mass energies (integrated luminosities) of 7 TeV (5 fb$^{-1}$), 8 TeV (20 fb$^{-1}$), and 13 TeV (36 fb$^{-1}$).
