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.

First constraints on invisible Higgs boson decays using $\mathrm{t}\bar{\mathrm{t}}\mathrm{H}$ production at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
This document presents first upper bounds on the branching fraction of the Higgs boson to invisible particles using an event topology corresponding to production of the Higgs boson in association with a top quark pair. This is done by reinterpreting results of the searches for scalar top quarks performed in the all-hadronic, the semi-leptonic, and the di-leptonic final states. [...]
