Abstract
D-meson production measurements in pp collisions are used to test perturbative quantum chromodynamics (pQCD) calculations. This contribution reports the preliminary results of the non-prompt \Dzero fraction at midrapidity in the transverse momentum range $p_\text{T} < 24$ \GeV, measured in pp collisions at $\sqrt{s} = 13.6$ TeV, using data from the LHC Run 3. Results are compared to the predictions of EPOS and various modes of PYTHIA simulations. Additionally, the double production of D mesons allows us to study 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 \Dzero mesons in pp collisions at $\sqrt{s} = 13.6$ TeV is also reported.
