  Highly energetic jets are sensitive probes for the kinematics and the
topology of nuclear collisions. Jets are collimated sprays of charged and
neutral particles, which are produced in the fragmentation of hard scattered
partons in the early stage of the collision. The measurement of nuclear
modification of charged jet spectra in p-Pb collisions provides an important
way of quantifying the effects of cold nuclear matter in the initial state on
jet production, fragmentation, and hadronization. Unlike in Pb-Pb collisions,
modifications of jet production due to hot nuclear matter effects are not
expected to occur in p-Pb collisions. Therefore, measurements of nuclear
modifications in charged jet spectra in p-Pb collisions (commonly known as
$R_\mathrm{pPb}$) can be used to isolate and quantify cold nuclear matter
effects. Potential nuclear effects are expected to be more pronounced in more
central p-Pb collisions due to a higher probability of an interaction between
the proton and the lead-nucleus. To measure the centrality dependence of
charged jet spectra, it is crucial to use a reliable definition of event
centrality, which ALICE developed utilizing the Zero-Degree Calorimeter (ZDC).
