The data sample used in the analysis corresponds to an integrated luminosity of $(19.3\\pm0.4)~\\mathrm{nb^{-1}}$. D mesons were reconstructed from their decays $\\mathrm{D^0 \\to K^-\\pi^+}$, $\\mathrm{D^+\\to K^-\\pi^+\\pi^+}$, and $\\mathrm{D_s^+\\to \\phi\\pi^+\\to K^-K^+\\pi^+}$ and their charge conjugates. Compared to previous measurements in the same rapidity region, the cross sections of prompt $\\mathrm{D^+}$ and $\\mathrm{D_s^+}$ mesons have an extended $p_{\\mathrm{T}}$ coverage and total uncertainties reduced by a factor ranging from 1.05 to 1.6, depending on $p_{\\mathrm{T}}$, allowing for a more precise determination of their $p_{\\mathrm{T}}$-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, $f_\\mathrm{s}/(f_\\mathrm{u}+f_\\mathrm{d})$, is compatible for charm and beauty quarks and with previous measurements at different centre-of-mass energies and collision systems. The $\\mathrm{b\\overline{b}}$ production cross section per rapidity unit at midrapidity, estimated from non-prompt D-meson measurements, is $\\mathrm{d}\\sigma_\\mathrm{b\\overline{b}}/\\mathrm{d} y|_\\mathrm{|y|&lt;0.5} = 34.5 \\pm 2.4 (\\mathrm{stat}) ^{+4.7}_{-2.9} (\\mathrm{tot.~syst})~\\mathrm{\\mu b}$. It is compatible with previous measurements at the same centre-of-mass energy and with the cross section predicted by perturbative QCD calculations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.105047.v1/t1","@type":"Dataset","description":"$p_\\mathrm{T}$-differential production cross section of non-prompt $\\mathrm{D^0}$ mesons in pp collision at $\\sqrt{s}=5.02~\\mathrm{TeV}$ in the rapidity interval $|y|&lt;0.5$.
