Observation of the doubly charmed baryon $\it{\Xi}_{cc}^+$ with the LHCb Run 3 detector
The first observation of the doubly charmed baryon $\it{\Xi}_{cc}^+$ is reported through its decay to the $\it{\Lambda}_c^+ K^-\pi^+$ final state, with a statistical significance exceeding seven standard deviations. [...]

Highly boosted dielectron identification in proton-proton collisions at $ \sqrt{s} = $ 13 TeV
A new technique is developed to identify dielectrons ($ \mathrm{e}^+\mathrm{e}^- $) with Lorentz boost $ \gamma_{\mathrm{L}} > $ 20 that produce one single merged cluster in the electromagnetic calorimeter of the CMS detector. [...]
