Search for a pseudoscalar boson in the mass range from 4 to 15 GeV produced in decays of the 125 GeV Higgs boson in the final states with two muons and two nearby tracks at $\sqrt{s}=13~\mathrm{TeV}$ /CMS Collaboration
A search is presented for pairs of light pseudoscalar bosons, in the mass range between 4 and 15$~\mathrm{GeV}$, produced in decay of the 125 GeV Higgs boson. The decay mode where one light boson decays into $\tau$ leptons, while the other one decays into a pair of $\tau$ leptons or muons, is considered. [...]

Search for Pair Production of Vector-Like Quarks in the Fully Hadronic Channel /CMS Collaboration
The results of two searches for vector-like T or B quark pair production using the fully hadronic final state are presented, using data from the CMS experiment at a center of mass energy of 13 TeV collected during the 2016 run, corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. A multiclassification algorithm, the ``boosted event shape tagger'', is deployed to label candidate jets as originating from top quarks, W, Z, or Higgs bosons. [...]

Search for a charged Higgs boson decaying into top and bottom quarks in proton-proton collisions at 13TeV in events with electrons or muons /CMS Collaboration
A search is presented for a charged Higgs boson heavier than the top quark and decaying into a top-bottom quark-antiquark pair. Events are selected by the presence of a single isolated charged lepton (electron or muon) or an opposite sign dilepton (electron or muon) pair, categorized according to the jet multiplicity and the number of jets containing a b-hadron decay, and multivariate techniques are used to enhance the signal-background discrimination in each category. This search is based on proton-proton collision data collected by the CMS experiment at the LHC at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 $\mathrm{fb}^{-1}$.
