Description
Relativistic heavy-ion collisions produce a
hot and dense state of strongly interacting
matter, the quark-gluon plasma. The
presence of the quark-gluon plasma has
been observed to affect the yields of final state
particles. High-$p_{\rm T}$ partons may lose
energy while traversing the medium,
resulting in the suppression of hadrons at
high $p_{\rm T}$ with respect to the reference
values obtained from binary-collision scaled
proton-proton measurements. This
modification is quantified as the nuclear
modification factor $R_{AA}$. Possible initial state
effects due to the nuclear nature of
the collision system are quantified in the
absence of a quark-gluon plasma with p-Pb collisions. The ALICE Collaboration
reports the nuclear modification factors
$R_{AA}$ and $R_{pPb}$ of several light-flavor
hadrons and compares these results to
measurements from lower energies and to theoretical models.
