Measurements of normalised multi-differential cross$~$sections for top quark pair production in pp collisions at $\sqrt{s}=13~\mathrm{TeV}$ and simultaneous determination of the strong coupling strength, top quark pole mass and parton distribution functions /CMS Collaboration
Normalised multi-differential cross sections for top quark pair (${\mathrm{t}}\bar{\mathrm{t}}$) production are measured in pp collisions at a centre-of-mass energy of $13~\mathrm{TeV}$ using events containing two opposite-sign leptons. The analysed dataset was recorded by the CMS detector in 2016 and corresponds to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. [...]

The CMS detector for the planned high luminosity LHC run will have a new first level (L1) hardware track trigger. The impact of the L1 track trigger is explored based on the potential increase of CMS sensitivity to signals beyond the standard model in final states with multiple jets and low total transverse energy.

Search for supersymmetry with direct stau production at the HL-LHC with the CMS Phase-2 detector /CMS Collaboration
A search for the direct production of $\tau$ sleptons ($\widetilde{\tau}$) is developed assuming $3000~\mathrm{fb}^{-1}$ of proton-proton collision data produced by the HL-LHC at a center-of-mass energy of $14~\mathrm{TeV}$. Three final states are investigated: two $\tau$ leptons decaying hadronically, and one $\tau$ lepton decaying hadronically and the other one decaying to a muon or electron and neutrinos. The analysis is performed using the Delphes simulation of the CMS Phase-2 detector where the object reconstruction performance is tuned to the one achieved with CMS Phase-2 full simulation. [...]

The search for a Higgs boson decaying to invisible particles, produced through the vector boson fusion mode in the High-Luminosity LHC proton-proton collisions at $\sqrt{s}=14~\mathrm{TeV}$, is investigated based on simulation studies using Delphes, a fast-simulation package used to provide a parameterised response of the upgraded CMS detector. The event selection follows the existing CMS Run II data analysis, optimised for the High-Luminosity LHC conditions. [...]
