abstract = {The measurement of the production of charm jets, identified
by the presence of a $\mathrm{D^0}$ meson in the jet
constituents, is presented in proton--proton collisions at
centre-of-mass energies of $\sqrt{s}=5.02$ and $13$ TeV with
the ALICE detector at the CERN LHC.The $\mathrm{D^0}$ mesons
were reconstructed from their hadronic decay
$\mathrm{D^0}\rightarrow\mathrm{K}^{-}\mathrm{\pi}^{0}$ and
the respective charge conjugate. Jets were reconstructed
from $\mathrm{D^0}$-meson candidates and charged particles
using the anti-$k_\text{T}$ algorithm, in the jet transverse
momentum range 5$<$$P_{T,ch,jet}$$ <$ 50GeV/c pseudorapidity
|$\mathrm{{\eta}_{ch jet}}$| $< 0.9-R$ and with the jet
resolution parameters , $R = 0.2, 0.4, 0.6$. The
distribution of the jet momentum fraction carried by a
$\mathrm{D^0}$ meson along the jet axis ($z^{ch}_{||}$) was
measured in the range $0.4 < z^{ch}_{||} < 1.0 $in four
ranges of the jet transverse momentum.Comparisons of results
for different collision energies and jet resolution
parameters are also presented. The measurements are compared
to predictions from Monte Carlo event generators based on
leading-order and next-to-leading-order perturbative quantum
chromodynamics calculations. A generally good description of
the main features of the data is obtained in spite of a few
discrepancies at low $P_{T,ch,jet}$. Measurements were also
done for at $R =0.3 $ at $\sqrt{s}=5.02$ TeV and are shown
along with their comparisons to theoretical predictions in
an appendix to this paper.},
