      abstract     = {The p$_{T}$-differential production cross sections of
                      prompt and non-prompt (produced in beauty-hadron decays) D
                      mesons were measured by the ALICE experiment at midrapidity
                      (|y|< 0.5) in proton-proton collisions at $ \sqrt{s} $ =
                      5.02 TeV. The data sample used in the analysis corresponds
                      to an integrated luminosity of (19.3 ± 0.4) nb$^{−1}$. D
                      mesons were reconstructed from their decays D$^{0}$→
                      K$^{−}$π$^{+}$, D$^{+}$→ K$^{−}$π$^{+}$π$^{+}$, and
                      $ {\mathrm{D}}_{\mathrm{s}}^{+}\to \phi {\pi}^{+}\to
                      {\mathrm{K}}^{-}{\mathrm{K}}^{+}{\pi}^{+} $ and their charge
                      conjugates. Compared to previous measurements in the same
                      rapidity region, the cross sections of prompt D$^{+}$ and $
                      {\mathrm{D}}_{\mathrm{s}}^{+} $ mesons have an extended
                      p$_{T}$ coverage and total uncertainties reduced by a factor
                      ranging from 1.05 to 1.6, depending on p$_{T}$, allowing for
                      a more precise determination of their p$_{T}$-integrated
                      cross sections. The results are well described by
                      perturbative QCD calculations. The fragmentation fraction of
                      heavy quarks to strange mesons divided by the one to
                      non-strange mesons, f$_{s}$/(f$_{u}$ + f$_{d}$), is
                      compatible for charm and beauty quarks and with previous
                      measurements at different centre-of-mass energies and
                      collision systems. The $ \mathrm{b}\overline{\mathrm{b}} $
                      production cross section per rapidity unit at midrapidity,
                      estimated from non-prompt D-meson measurements, is $
                      \mathrm{d}{\sigma}_{\mathrm{b}\overline{\mathrm{b}}}/\mathrm{d}y\left|{}_{\left|\mathrm{y}\right|<0.5}=34.5\pm
                      2.4{\left(\mathrm{stat}\right)}_{-2.9}^{+4.7}\left(\mathrm{tot}.\mathrm{syst}\right)\right.
                      $ μb. It is compatible with previous measurements at the
                      same centre-of-mass energy and with the cross section
                      predicted by perturbative QCD calculations.},
