Multiplicity dependence of charm baryon and meson production in pPb collisions at 8.16 TeV /CMS Collaboration
Measurements of charm baryon, $\Lambda_{\rm c}^{+}$, and meson, $\mathrm{D}^0$, production yields in proton-lead collisions at a nucleon-nucleon center-of-mass energy of 8.16 TeV are presented over a wide range of event charged track multiplicities. The data were collected in 2016 with the CMS experiment with an integrated luminosity of $186\;\mathrm{nb}^{-1}$. [...]

Search for HH production in the bbWW decay mode /CMS Collaboration
In this note we present the results of a search for Higgs boson pair (HH) production with one Higgs boson decaying to two bottom quarks and the other to two W bosons. The search is based on proton-proton collision data recorded at $\sqrt{s} = 13~$TeV center-of-mass energy, corresponding to an integrated luminosity of $138~$fb$^{-1}$. [...]

Study of charm hadronization with prompt $\Lambda_c^+$ baryons in proton-proton and lead-lead collisions at $\sqrt{s_\mathrm{NN}}= 5.02~\mathrm{TeV}$ /CMS Collaboration
The production of prompt $\Lambda_c^+$ baryons is measured via the exclusive decay channel $\Lambda_c^+ \to \mathrm{p} \mathrm{K}^- \pi^+$ at a center-of-mass energy per nucleon pair of $5.02~\mathrm{TeV}$ using $252~\mathrm{nb}^{-1}$ proton-proton (pp) and $0.607~\mathrm{nb}^{-1}$ lead-lead (PbPb) collisions collected at the CERN LHC in 2017 and 2018, respectively. The measurements are performed within the $\Lambda_c^+$ rapidity interval $|y|<1.0$ with transverse momentum ($p_\mathrm{T}$) ranges of 3--30 and 6--40 $\mathrm{GeV}/c$ for pp and PbPb collisions, respectively.

Observation of four top quark production in proton-proton collisions at $\sqrt{s}=13\,\mathrm{TeV}$ /CMS Collaboration
The first observation of the production of four top quarks in proton-proton collisions is reported, based on a data sample collected by the CMS experiment at a center-of-mass energy of $13\,\mathrm{TeV}$ in 2016 to 2018 at the CERN LHC and corresponding to an integrated luminosity of $138\,\mathrm{fb}^{-1}$. Events with two same-sign, three, and four charged leptons (electrons and muons) and additional jets are analyzed with multivariate discriminants to distinguish the signal process from the main backgrounds.
