abstract = {Measurements of the centrality and rapidity dependence of
inclusive jet production in $\sqrt{s_\mathrm{NN}} = 5.02$
TeV proton--lead ($p$+Pb) collisions and the jet
cross-section in $\sqrt{s} = 2.76$ TeV proton--proton
collisions are presented. These quantities are measured in
datasets corresponding to an integrated luminosity of 27.8
nb$^{-1}$ and 4.0 pb$^{-1}$, respectively, recorded with the
ATLAS detector at the Large Hadron Collider in 2013. The
$p$+Pb collision centrality was characterised using the
total transverse energy measured in the pseudorapidity
interval $-4.9 < \eta < -3.2$ in the direction of the lead
beam. Results are presented for the double-differential
per-collision yields as a function of jet rapidity and
transverse momentum ($p_\mathrm{T}$) for minimum-bias and
centrality-selected $p$+Pb collisions, and are compared to
the jet rate from the geometric expectation. The total jet
yield in minimum-bias events is slightly enhanced above the
expectation in a $p_\mathrm{T}$-dependent manner but is
consistent with the expectation within uncertainties. The
ratios of jet spectra from different centrality selections
show a strong modification of jet production at all
$p_\mathrm{T}$ at forward rapidities and for large
$p_\mathrm{T}$ at mid-rapidity, which manifests as a
suppression of the jet yield in central events and an
enhancement in peripheral events. These effects imply that
the factorisation between hard and soft processes is
violated at an unexpected level in proton--nucleus
collisions. Furthermore, the modifications at forward
rapidities are found to be a function of the total jet
energy only, implying that the violations may have a simple
dependence on the hard parton-parton kinematics.},
