Observation of X(6900) and evidence of X(7100) in the psi(2S)Jpsi to 4mu mass spectrum in pp collisions at CMS /CMS Collaboration
A search is performed for structures near threshold in the $J/\psi\psi(2S) \rightarrow \mu^{+} \mu^{-} \mu^{+} \mu^{-}$ channel using a sample of proton-proton collisions at $\sqrt{s} = 13.0~\mathrm{TeV}$ and $13.6~\mathrm{TeV}$ recorded by the CMS detector at the CERN LHC. The data correspond to an integrated luminosity of about $314~\mathrm{fb}^{-1}$. [...]

Search for compressed electroweakinos with low-momentum isolated tracks /CMS Collaboration
A search is presented for higgsino dark matter (DM) in final states with a low momentum (soft), isolated track and large missing transverse momentum. In the minimal supersymmetric standard model (MSSM), charginos are most often produced in association with a nearly mass-degenerate neutralino or another chargino, and predominantly decay into the lightest neutralino (DM candidate) and a soft pion. For a mass difference $\Delta m^{\pm}$ less than $1$ $\mathrm{GeV}$, a discernible displacement of the pion's track with respect to the primary vertex can arise, reaching up to about $1$ $\mathrm{cm}$ for the smallest allowed $\Delta m^{\pm}$.

Measurement of event shape variables using charged particles inside jets in proton-proton collisions at s = 13 TeV /CMS Collaboration
Event shape variables, constructed from the four-momenta of the final-state objects in an event, are sensitive to the predictions of quantum chromodynamics in multijet production, while minimizing the impact of systematic uncertainties. A study of five event shape variables is presented, using proton-proton collision data collected at a centre-of-mass energy of 13$~\mathrm{TeV}$ with the CMS detector during 2016-2018, corresponding to an integrated luminosity of 138 $\mathrm{fb^{-1}}$.
