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. [...]

Open heavy flavor and quarkonia in heavy ion collisions at HL-LHC
/CMS Collaboration
The projected performance for heavy flavour hadrons and quarkonium measurements in the high luminosity phase of the LHC in pp and PbPb collisions at $\sqrt{s_{_\textrm{NN}}} = 5.02$ TeV is presented, focusing on $\textrm{J}\kern-1pt/\kern-2pt\psi$ and $\Upsilon$ states (including the elliptic flow $v_2$), as well as B$_\textrm{s}$ mesons and $\Lambda_\textrm{c}^+$ baryons. Projections for the nuclear modification factor of B$^+$, B$^0$ and B$_\textrm{s}$ mesons in pPb data at $\sqrt{s_{_\textrm{NN}}} = 5.02$ TeV are also reported..

Predictions on the precision achievable for small system flow observables in the context of HL-LHC
/CMS Collaboration
In this note, we discuss how the future HL-LHC program will enable highly precise measurements of flow observables in small systems. Projections of the statistical uncertainties achievable for symmetric cumulant analyses at $\sqrt{\text{s}} = 13$ TeV for pp collisions and at $\sqrt{\text{s}_{NN}} = 5.02$ TeV for pPb collisions are presented.

CP-violation studies at the HL-LHC with CMS using $\mathrm{B^0_s}$ decays to $\mathrm{J}/\psi\phi(1020)$
/CMS Collaboration
We have estimated the expected sensitivity on the CP-violating phase $\phi_s$ measured in the decay channel $\mathrm{B^0_s}~\to \! \mathrm{J}/\psi\phi(1020)$ in pp collisions with the CMS detector at the end of the HL-LHC data-taking with 3 ab$^{-1}$ of collected data. The sensitivity on $\phi_s$ mainly depends on the collected statistics, on the flavour-tagging power, and on the proper-decay-time resolution. [...]

Measurement of rare $B \to \mu^+\mu^-$ decays with the Phase-2 upgraded CMS detector at the HL-LHC
/CMS Collaboration
The sensitivity of the upgraded CMS detector for measuring the rare decays $B_{s}^0\to \mu^+ \mu^-$ and $B^0\to \mu^+ \mu^-$ in the HL-LHC scenario is studied. The upgraded detector, especially with its improved momentum resolution, and the foreseen total integrated luminosity of $3000~\mathrm{fb}^{-1}$ are expected to enable high precision measurements of the branching fractions of $B_{s}^0\to \mu^+ \mu^-$ and the effective lifetime of the $B_{s}^0\to \mu^+ \mu^-$ decay with reduced systematic and statistical uncertainties.
