Prospects for the search for gluon-mediated FCNC in top quark production with the CMS Phase-2 detector at the HL-LHC /CMS Collaboration
Prospects are presented for a search for gluon-mediated flavour-changing neutral currents in the top quark production via $\mathrm{tug}$ and $\mathrm{tcg}$ vertices using the CMS Phase-2 detector at the HL-LHC. The analysis uses Monte Carlo samples of proton-proton collisions at $\sqrt{s} = 14~\mathrm{TeV}$ with a full simulation of the Phase-2 upgraded CMS detector assuming an average of 200 proton-proton interactions per bunch crossing.

Measurements of Higgs boson properties from on-shell and off-shell production in the four-lepton final state /CMS Collaboration
Studies of on-shell and off-shell Higgs boson production in the four-lepton final state are presented, using data from the CMS experiment at the LHC that corresponds to an integrated luminosity of $80.2~\mathrm{fb}^{-1}$ at 13 TeV. Joint constraints are set on the width of the Higgs and parameters that express its anomalous couplings to two electroweak vector bosons using both on-shell and off-shell production of the Higgs boson [...]

Search for the pair production of light top squarks in the $\mathrm{e}\mu$ final state in proton-proton collisions at $\sqrt{s} = 13~\mathrm{TeV}$ /CMS Collaboration
A search for the production of a pair of top squarks in proton-proton collisions at the CERN LHC is presented. This search targets a region of the parameter space where the kinematics of top squark pair production and top quark pair production are very similar, due to the mass of the neutralino being small.

Inclusive search for supersymmetry using razor variables in pp collisions at $\sqrt{s}=13$ TeV /CMS Collaboration
An inclusive search for supersymmetry with the razor variables is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$ collected with the CMS experiment in 2016 at a center-of-mass energy of $\sqrt{s}=13~\mathrm{TeV}$. The search covers final states with zero or one charged lepton and features event categories divided according to the presence of a high-transverse momentum hadronically decaying W boson or top quark, the number of jets, the number of b-tagged jets, and the values of the razor kinematic variables in order to separate signal from background for a wide variety of supersymmetric particle signatures.
