Search for top squarks decaying via the four-body mode in single-lepton final states from Run 2 of the LHC /CMS Collaboration
Results are presented from a search for the pair production of the lightest supersymmetric partner of the top quark ($\mathrm{\widetilde{t}}_{1}$). The search targets the four-body decay of the $\mathrm{\widetilde{t}}_{1}$, which is allowed when the mass difference between the top squark and the lightest supersymmetric particle is smaller than the mass of the $\mathrm{W}$ boson.

Projection of the top quark spin correlation measurement and search for top squark pair production at the HL-LHC /CMS Collaboration
The CMS prospects for the high-luminosity phase of the LHC on the measurement of the top quark spin correlation is presented, using events containing two oppositely charged lepton pairs (e$\mu$) produced in proton-proton collisions at a center-of-mass energy of 14 TeV assuming an integrated luminosity of $3~\mathrm{ab}^{-1}$. We investigate the normalised strength of the spin correlation in the sample and hence, provide a first performance study in future spin correlation measurements at 14 TeV. [...]
