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 [...]

Prospects for exclusion or discovery of a third generation leptoquark decaying into a $\tau$ lepton and a b quark with the upgraded CMS detector at the HL-LHC /CMS Collaboration
Projections for searches for production of third generation leptoquarks (LQs) in proton-proton collisions at a center-of-mass energy of 14 TeV are presented. The projections use simulated data samples corresponding to integrated luminosities of 300 and 3000 $\mathrm{fb}^{-1}$. The analysis utilizes the DELPHES simulation package for the upgraded CMS detector at the High-Luminosity LHC, and considers both the single production channel, with a final state consisting of one b quark and two $\tau$ leptons, and the pair production channel, producing two b quarks and two $\tau$ leptons.

Constraining nuclear parton distributions with heavy ion collisions at the HL-LHC with the CMS experiment /CMS Collaboration
Recent measurements in heavy ion collisions by the CERN LHC Collaborations have been used to assess nuclear effects and provide valuable data for nuclear parton distribution analyses. In this note, performance studies for measurements with the CMS detector at the High-Luminosity LHC (HL-LHC) are presented. [...]

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..

Performance of jet quenching measurements in pp and PbPb collisions with CMS at the HL-LHC /CMS Collaboration
The projected performance of different jet measurements to be carried out with the large data samples expected in PbPb and pp collisions during the high-luminosity phase of the LHC (HL-LHC) is presented. The analyses are based on Monte Carlo simulations and extrapolations from data collected in pp and PbPb collisions between 2010 and 2016. [...]

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. [...]
