HH2b2W in di-leptonic channel /CMS Collaboration
A search for non-resonant Higgs boson pair production is presented, targeting final states where one Higgs boson decays to a pair of bottom quarks and the other Higgs boson decays to two $\mathrm{W}$ bosons, both of which decay leptonically (to an electron or a muon and a neutrino). For the first time, the search is conducted with proton-proton collision data from the LHC at $\sqrt{s}=13.6~\text{TeV}$. [...]

Study of spin correlations in Higgs boson decays to four leptons at CMS /CMS Collaboration
Kinematic distributions in Higgs boson decay to four leptons $\mathrm{H} \to 4\ell$ are studied using matrix element techniques, optimizing sensitivity to the tensor structure of Higgs boson interactions and spin correlations in the decay process. The data were collected by the CMS experiment at the LHC, corresponding to integrated luminosities of 138 and 62 fb$^{-1}$ at proton-proton center of mass energies of 13 and 13.6 TeV, respectively, covering the 2016--2018 and 2022--2023 data-taking periods.

Measurement of the Upsilon(1S), Upsilon(2S), and Upsilon(3S) differential production cross sections in pp collisions at 13.6 TeV /CMS Collaboration
The production cross sections of the $\Upsilon$(1S), $\Upsilon$(2S), and $\Upsilon$(3S) mesons are measured in proton-proton collisions at $\sqrt{s}=13.6$ TeV, using a data sample collected in 2022 by the CMS experiment and corresponding to an integrated luminosity of 37.4 $\text{fb}^{-1}$.
