Anomalous couplings in the tt+Z final state at the HL-LHC /CMS Collaboration
The electroweak couplings of the top quark provide a crucial window to physics beyond the standard model and can be put to stringent tests with the CERN High-Luminosity LHC (HL-LHC). The expected sensitivity of the CMS detector for anomalous electroweak top quark interactions based on differential cross section measurements of the $\mathrm{t\overline{t}Z}$ process in the three lepton final state is provided for a HL-LHC scenario with 3000 fb$^{-1}$ of proton-proton collision data at a centre-of-mass energy of 14 TeV..

Search for excited leptons in llgamma final states in proton-proton collisions at the HL-LHC /CMS Collaboration
A search for excited leptons (electrons and muons) is presented, using simulation of the upgraded CMS detector at the High-Luminosity LHC (HL-LHC). Excited leptons are predicted by many theories beyond the standard model (SM) where quarks and leptons are not elementary but instead are themselves composite objects. [...]

Study of the expected sensitivity to the P$\mathrm{_5'}$ parameter in the $\mathrm{B^0 \to K^{*0}}\mu^+\mu^-$ decay at the HL-LHC /CMS Collaboration
The expected sensitivity to the $\mathrm{P'_5}$ parameter in $\mathrm{B^0}\to {\rm K}^{*0}\mu^+\mu^-$ decays from an integrated luminosity of 300 and 3000 fb$^{-1}$ of pp collisions at a center-of-mass energy of 14 TeV at the HL-LHC is presented. Angular observables in the $\mathrm{B^0}\to {\rm K}^{*0}\mu^+\mu^-$ decay, such as the $\mathrm{P'_5}$ parameter, are of particular interest as their theoretical predictions are less affected by hadronic uncertainties.

High-$p_T$ jet measurements at the HL-LHC /CMS Collaboration
Processes containing jets with high transverse momenta are studied for the upgraded CMS Phase-2 detector design at the High-Luminosity LHC assuming a center-of-mass energy of 14 TeV and an integrated luminosity of 3 ab$^{-1}$. The high luminosity allows to fully exploit high transverse momentum jets (boosted jets) and to differentiate between various jet types. [...]

Vector Boson Scattering prospective studies in the ZZ fully leptonic decay channel for the High-Luminosity and High-Energy LHC upgrades /CMS Collaboration
Prospective studies for the vector boson scattering (VBS) in the ZZ channel at the HL-LHC are presented, where the Z bosons are identified and measured through their leptonic decays, $\ell = e, \mu$. The results obtained from the 2016 analysis with an integrated luminosity of $36~\mathrm{fb}^{-1}$ are projected to the HL-LHC luminosity of $3000~\mathrm{fb}^{-1}$ and center-of-mass energy of 14 TeV, taking into account the increased acceptance of the CMS detector.

Projection of the Run 2 MSSM $\text{H} \to \tau\tau$ limits for the High-Luminosity LHC /CMS Collaboration
A search for heavy Higgs bosons decaying to $\tau$ leptons was previously performed using data collected during Run 2 of the LHC, based on a data set of proton-proton collisions at $\sqrt{s}=13~\mathrm{TeV}$ corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. A projection of these results to a High-Luminosity LHC data set of $3000~\mathrm{fb}^{-1}$ is described. [...]
