Measurement of the $\Omega_c^0$ and $\Xi_c^0$ baryon lifetimes using hadronic $b$-baryon decays / LHCb Collaboration
The lifetimes of the $\Omega_c^0$ and $\Xi_c^0$ baryons are measured using a $pp$ collision dataset collected by the LHCb experiment, corresponding to an integrated luminosity of $9~\rm{fb^{-1}}$. The charm baryons are produced in the fully reconstructed decay chains $\Omega_b^- \rightarrow \Omega_c^0 (\rightarrow pK^-K^-\pi^+)~\pi^-$ and $\Xi_b^- \rightarrow \Xi_c^0 (\rightarrow pK^-K^-\pi^+)~\pi^-$.

Search for the rare decay $ \mathrm{D^0}\to\mu^{+}\mu^{-} $ in proton-proton collisions at $ \sqrt{s} = $ 13.6 TeV / CMS Collaboration
A search for the rare decay $ \mathrm{D^0}\to\mu^{+}\mu^{-} $ is reported using proton-proton collision events at $ \sqrt{s} = $ 13.6 TeV collected by the CMS detector in 2022-2023, corresponding to an integrated luminosity of 64.5 fb$ ^{-1} $. [...]

Charmed meson pair production in high-energy pp collisions within the QCD color dipole approach / Sampaio dos Santos, Glauber (Rio Grande do Sul U.) ; da Silveira, Gustavo Gil (Rio Grande do Sul U. ; CERN ; Rio de Janeiro State U.) ; Machado, Magno Valério Trindade (Rio Grande do Sul U.)
A study of double-charmed meson production in high-energy proton–proton collisions at the Large Hadron Collider is presented. Considering the color dipole formalism developed in the transverse momentum representation along with the double parton scattering mechanism, predictions are made for the transverse momentum differential cross section for different pairs of $ D $-mesons.

Observation of the charged-particle multiplicity dependence of $ \sigma_{\psi(2\text{S})} /\sigma_{\mathrm{J}/\psi} $ in $p$-Pb collisions at 8.16 TeV / CMS Collaboration
Bound states of charm and anticharm quarks, known as charmonia, have a rich spectroscopic structure that can be used to probe the dynamics of hadron production in high-energy hadron collisions. Here, the cross section ratio of excited $ (\psi(2\text{S})) $ and ground state $ (\mathrm{J}/\psi ) $ vector mesons is measured as a function of the charged-particle multiplicity in proton-lead (pPb ) collisions at a center-of-mass (CM) energy per nucleon pair of 8.16 TeV.
