Azimuthal angular correlations in high transverse momentum dijet events /CMS Collaboration
The azimuthal angle correlation between the two jets with the largest transverse momenta in inclusive 2-jet topologies, close to the back-to-back configuration, is measured for several regions of the leading jet transverse momentum. Measurements of the same observable requiring the presence of extra jets are also presented. [...]

Measurement of the differential $\mathrm{t\bar{t}}$ cross section with high-$p_\mathrm{T}$ top-quark jets in the all-hadronic channel at $\sqrt{s}=8~\mathrm{TeV}$ /CMS Collaboration
A measurement of the differential $\mathrm{t\bar{t}}$ production cross section using $19.7~\mathrm{fb}^{-1}$ of all-jet events with high-$p_\mathrm{T}$ top-quark jets collected by the CMS detector at $\sqrt{s} = 8~\mathrm{TeV}$ is presented. This measurement focuses on events where both top quarks decay hadronically, giving rise to a dijet topology. [...]

Measurement of groomed jet mass in PbPb and pp collisions at $\sqrt{s_{NN}} = 5.02~\mathrm{TeV}$ /CMS Collaboration
A measurement of the groomed jet mass ($M_g$) normalized by the jet transverse momentum ($p_\text{T}^\text{jet}$) for anti-$k_\text{T}$ jets with the radius parameter $0.4$ in PbPb and pp collisions at a center of mass energy of $5.02\,\mathrm{TeV}$ per nucleon pair is presented. The jet grooming algorithm is a recursive procedure which sequentially removes soft constituents of a jet until a pair of hard subjets is found. [...]

Search for $R$-parity-violating supersymmetry in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ in events with a single lepton and large jet and bottom quark jet multiplicity /CMS Collaboration
Results are reported from a search for physics beyond the standard model in proton-proton collisions at a center-of-mass energy $\sqrt{s}=13~\mathrm{TeV}$, focusing on the signature of a single lepton, large jet multiplicity, and large bottom quark jet multiplicity, without a requirement on the missing transverse momentum in an event. The data sample corresponds to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ recorded by the CMS experiment at the LHC. [...]

Evidence for the decay of the Higgs Boson to Bottom Quarks /CMS Collaboration
A search for the standard model (SM) Higgs boson ($\mathrm{H}$) decaying to $\mathrm{b\overline{b}}$ when produced in association with a weak vector boson ($\mathrm{V}$) is reported for the following processes: $\mathrm{Z}(\nu\nu)\mathrm{H}$, $\mathrm{W}(\mu\nu)\mathrm{H}$, $\mathrm{W}(e\nu)\mathrm{H}$, $\mathrm{Z}(\mu\mu)\mathrm{H}$, and $\mathrm{Z}(ee)\mathrm{H}$. The search is performed in data samples corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ at $\sqrt{s}=13~\mathrm{TeV}$ recorded by the CMS experiment at the LHC during $\mathrm{Run~2}$ in 2016.

Estimated Sensitivity for New Particle Searches at the HL-LHC /CMS Collaboration
Sensitivity projections for new physics searches with 3000 $\mathrm{fb}^{-1}$ of data anticipated at the high-luminosity LHC (HL-LHC) are presented. These results were obtained from dedicated studies performed for the ECFA 2016 upgrade workshop. [...]

Search for heavy resonances decaying into a Z boson and a vector boson in the $\nu \nu$ $q\bar{q}$ final state /CMS Collaboration
A search is presented for heavy resonances decaying into a Z boson and either a W boson or another Z boson (WZ or ZZ), with one Z boson decaying into a pair of neutrinos and the other boson decaying hadronically into a pair of collimated quarks, which is reconstructed as a highly energetic boosted jet. The search is performed using the data collected by the CMS detector at the CERN LHC during 2016 in proton-proton collisions at a center-of-mass energy of $13~\mathrm{TeV}$, corresponding to a total integrated luminosity of $35.9~\mathrm{fb}^{-1}$.
