Search for a massive scalar resonance decaying to a light scalar and a Higgs boson in the four b quark final state with boosted topology /CMS Collaboration
We search for the resonant production of a new massive scalar X decaying into a new light scalar Y and the standard model Higgs boson H through the process $\text{X}\!\!\to\!\!\text{Y}\text{H}\!\!\to\!\!\text{b}\overline{\text{b}}\text{b}\overline{\text{b}}$.

Evidence for off-shell Higgs boson production and first measurement of its width /CMS Collaboration
The first measurement of the Higgs boson ($\mathrm{H}$) width is performed based on evidence for off-shell $\mathrm{H}$ production in the final state with two $\mathrm{Z}$ bosons decaying into either four charged leptons ($\mathrm{e}$ or $\mu$), or two charged leptons and two neutrinos. Results are based on data from the CMS experiment at the LHC at a center-of-mass energy of $13~\mathrm{TeV}$, corresponding to an integrated luminosity of up to $140~\mathrm{fb}^{-1}$. [...]

Search for invisible decays of a Higgs boson produced via vector boson fusion with $138~\mathrm{fb}^{-1}$ of proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A search for invisible decays of the Higgs boson produced via vector boson fusion (VBF) has been performed with the $\sqrt{s}=13~\mathrm{TeV}$ data sets collected by the CMS experiment at the LHC. The sensitivity to the VBF production mechanism is enhanced by using two strategies to construct two analysis categories, one based on missing transverse momentum, and a second based on the properties of jets.

A new set of CMS tunes for novel colour reconnection models in PYTHIA8 based on underlying-event data /CMS Collaboration
New sets of parameter tunes for two of the colour reconnection models implemented in the PYTHIA8 event generator, QCD-inspired and gluon move, are obtained based on the default CMS PYTHIA8 underlying-event tune, CP5. Measurements sensitive to underlying-event performed at $\sqrt{s}=$1.96, 7, and 13$~\mathrm{TeV}$ are used to constrain the parameters of the colour reconnection models and the multiple parton interactions simultaneously.
