Query: Ratios of jet and hadron spectra at LHC energies: measuring high-$p_T$
  suppression without a $pp$ reference   In this work we analyze the reliability of several techniques for computing
jet and hadron spectra at different collision energies. This is of particular
relevance for discovering energy loss in the upcoming oxygen-oxygen (OO) run at
the LHC, for which a reference $pp$ run at the same energy is currently not
planned. For hadrons and jets we compute the ratio of spectra between different
$pp$ collision energies in perturbative QCD, which can be used to construct a
$pp$ reference spectrum. Alternatively, a $pp$ reference can be interpolated
from measured spectra at nearby energies. We estimate the precision and
accuracy of both strategies for the spectra ratio relevant to the oxygen run,
and conclude that the central values agree to 4% accuracy for hadrons and 2%
accuracy for jets. As an alternative, we propose taking the ratio of OO and
$pp$ spectra at different collision energies, which cleanly separates the
experimental measurement from the theoretical computation.
