Query: Measurement of jet fragmentation in 5.02 TeV proton-lead and
  proton-proton collisions with the ATLAS detector   A measurement of the fragmentation functions of jets into charged particles
in $p$+Pb collisions and $pp$ collisions is presented. The analysis utilizes 28
nb$^{-1}$ of $p$+Pb data and 26 pb$^{-1}$ of $pp$ data, both at
$\sqrt{s_\mathrm{NN}}$ = 5.02 TeV, collected in 2013 and 2015, respectively,
with the ATLAS detector at the LHC. The measurement is reported in the
centre-of-mass frame of the nucleon-nucleon system for jets in the rapidity
range $|y^{*}|<$1.6 and with transverse momentum 45 $ < p_{\mathrm{T}} <$ 260
GeV. Results are presented both as a function of the charged-particle
transverse momentum and as a function of the longitudinal momentum fraction of
the particle with respect to the jet. The $pp$ fragmentation functions are
compared with results from Monte Carlo event generators and two theoretical
models. The ratios of the $p$+Pb to $pp$ fragmentation functions are found to
be consistent with unity.
