Probing early parton emissions in heavy ion collisions using the Lund jet plane
In scattering experiments, high-virtuality partons, i.e.,, quarks and gluons, initiate a series of additional parton emissions to create collimated sprays of particles known as jets. [...]

Search for heavy scalar resonances decaying to Lorentz-boosted Higgs and Higgs-like bosons in the $ \mathrm{b}\overline{\mathrm{b}}4\mathrm{q} $ final state at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search is performed for a heavy scalar resonance ($\mathrm{X}$) decaying to a Higgs boson ($\mathrm{H}$) and a Higgs-like scalar boson ($\mathrm{Y}$) in the two bottom quark ($ \mathrm{H}\to\mathrm{b}\overline{\mathrm{b}} $) and four quark ($ \mathrm{Y} \to\mathrm{V}\mathrm{V}\to4\mathrm{q} $) final state, where $\mathrm{V}$ denotes a $\mathrm{W}$ or $\mathrm{Z}$ boson.

Measurement of the $ \Upsilon{\textrm{(1S)}} $, $ \Upsilon{\textrm{(2S)}} $, and $ \Upsilon{\textrm{(3S)}} $ differential cross sections in pp collisions at $ \sqrt{s} = $ 13.6 TeV / CMS Collaboration
The production cross sections of the $ \Upsilon{\textrm{(1S)}} $, $ \Upsilon{\textrm{(2S)}} $, and $ \Upsilon{\textrm{(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 fb$ ^{-1} $.
