Description
The quantification of the effect of parton energy loss, known as jet
quenching, is one of the major goals of jet and high $p_T$
measurements in heavy-ion collisions. Here, the aim of the reconstruction of
jets, as compared to single particle measurements, is to provide a more direct
access to the original parton properties and the modification of the
fragmentation process in heavy-ion collisions.
For a clear interpretation of the reconstructed jet properties and the
measurement of the inclusive jet spectrum in heavy-ion collisions a detailed characterization of the
background and its fluctuation is paramount. In particular collective
effects within one event can enhance or deplete locally the level of
background and modify the jet energy scale.
The ALICE detector with its excellent tracking capabilities is the
ideal tool to study jet reconstruction based on charged particles in the presence of
correlated and uncorrelated background down to particle $p_T$ of 150
MeV/$c$.
We will evaluate the evolution of background effects using different
probes embedded into heavy-ion data and quantify their influence on
the reconstructed jet spectrum.
