Search for anomalous couplings in semileptonic WW and WZ decays at sqrt(s) = 13 TeV /CMS Collaboration
In this search additional operators that would lead to anomalous $\mathrm{W}\mathrm{W}\gamma$ or WWZ couplings are constrained by studying events with one W boson decaying to $\mathrm{e}\nu$ or $\mu\nu$, and one W or Z boson decaying hadronically, reconstructed as a single massive large-radius jet. The search uses a data set of proton-proton collisions with a centre-of-mass energy of 13 TeV as recorded by the CMS experiment at the CERN LHC in the year 2016, corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$.

Measurement of the average very forward energy as a function of the track multiplicity at central rapidities in proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
The average total energy as well as the hadronic and electromagnetic components of it are measured with the CMS detector at pseudorapidities $-6.6<\eta<-5.2$ in proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=13\,\mathrm{TeV}$. The results are presented as a function of the multiplicity of charged particle tracks in the region $|\eta|<2$. [...]

Search for heavy resonances in the all-hadronic vector-boson pair final state with a multi-dimensional fit /CMS Collaboration
We present a novel fit method in the search for new resonances decaying to WW, WZ, or ZZ boson pairs in the all-hadronic final state using data corresponding to an integrated luminosity of $77.3~\mathrm{fb}^{-1}$ taken with the CMS experiment at the LHC at a centre-of-mass energy of $\sqrt{s}=13~\mathrm{TeV}$. The search is focussed on resonances with masses above $1.2~\mathrm{TeV}$, where the decay products of each W or Z boson are expected to be collimated into one single large-radius jet. [...]

Study of the $\mathrm{B}^{+}\rightarrow \mathrm{J}/\psi \bar{\Lambda} \mathrm{p}$ decay in proton-proton collisions at $\sqrt{s}= 8~\mathrm{TeV}$ /CMS Collaboration
A study of the $\mathrm{B}^{+} \rightarrow \mathrm{J}/\psi \bar{\Lambda} \mathrm{p}$ decay is reported, using proton-proton collision data collected at $\sqrt{s}= 8~\mathrm{TeV}$ by the CMS experiment at the LHC, corresponding to an integrated luminosity of $19.6~\mathrm{fb}^{-1}$. The ratio of branching fractions $\frac{{\cal B}(\mathrm{B}^{+} \rightarrow \mathrm{J}/\psi \bar{\Lambda} \mathrm{p})}{{\cal B}(\mathrm{B}^{+} \rightarrow \mathrm{J}/\psi \mathrm{K}^{*+})}$ is measured to be $1.054\pm0.057~\text{(stat)} \pm0.028~\text{(syst)}\pm0.011({\cal B})\%$, where the first uncertainty is statistical, the second is systematic, and the third reflects the uncertainties in the world-average branching fractions.

Search for heavy Higgs bosons decaying to a top quark pair in proton-proton collisions at $\sqrt{s} = 13\,\mathrm{TeV}$ /CMS Collaboration
Multiple new-physics models extending the standard model predict the existence of additional scalar (H) or pseudoscalar (A) Higgs bosons. In this note, a search is presented for such new bosons decaying to a top quark pair in proton-proton collisions at a center-of-mass energy of $13\,\mathrm{TeV}$. [...]
