Description
D-meson production measurements in pp collisions are used to test perturbative quantum chromodynamics (pQCD) calculations. This contribution reports preliminary results of the ALICE Collaboration on the non-prompt $\text{D}^0$ fraction at midrapidity in the transverse-momentum range $p_\text{T} < 24$ GeV/\textit{c}, measured in pp collisions at $\sqrt{s} = 13.6$ TeV, using data from the LHC Run 3. Results are compared to the predictions from EPOS and various tunes of PYTHIA simulations. Additionally, studying the double production of D mesons in the same collision allows us to investigate double charm production via single (SPS) and double parton scattering (DPS). Like-sign meson pairs are expected to be predominantly produced by DPS processes, while opposite-sign pairs are more likely to be created via SPS. The status of the measurement of double production of $\text{D}^0$ mesons in pp collisions at $\sqrt{s} = 13.6$ TeV is also reported.
