First observation of the $\phi$ (1020) meson in the $K^+K^-$ mass spectrum of ultra-pheripheral PbPb collisions at forward rapidity /LHCb Collaboration
The first observation of the $\phi(1020)$ meson in the invariant-mass distribution of $K^+K^-$ meson pairs produced in ultra-peripheral PbPb interactions at forward rapidity, in the range 2.0-4.5, is presented. The PbPb data were collected by the LHCb experiment in 2018 at a nucleon-nucleon center-of-mass energy $\sqrt{snn}$=5.02 TeV, and correspond to an integrated luminosity of $228\pm10 \mu b^{-1}$ [...]

Combined effective field theory interpretation of Higgs boson, electroweak vector boson, top quark, and multijet measurements
Constraints on Wilson coefficients (WCs) corresponding to dimension-6 operators of the standard model effective field theory (SMEFT) are determined from a simultaneous fit to seven sets of CMS measurements probing Higgs boson, electroweak vector boson, top quark, and multijet production. [...]

Search for rare muonic B decays at CMS / Szlezak, Klara Emilia (Warsaw U.) /CMS Collaboration
In this paper, we present the search for three highly suppressed Standard Model processes at the CMS experiment: $B^{0} \to \mu^+ \mu^-$, $B_{s}^{0} \to \mu^+ \mu^-$, and $B_{s}^{0} \to \mu^+ \mu^- \gamma$. The latest and most precise results to date are presented for the first two decays, while the feasibility and experimental strategy for the third, yet unobserved at CMS, are discussed. [...]
