Description
A jet is a spray of collimated hadrons originated in the fragmentation of an energetic
parton. The cross section measurement provides a good test for pQCD calculations,
and jet production in pp collisions constitutes a reference for jet quenching
study in nucleus-nucleus collisions. In addition, the measurements in different
multiplicity intervals will provide insights to understand the properties of small
interacting system.
In this report, we will present charged jet cross section measurement in pp
collisions at 13 TeV with high statistics collected by ALICE. We will show the jet
cross section ratio for various jet resolution parameters. Such kind of cross section
ratio is an indirect measurement to jet shape. The charged particle jet production
in different multiplicity intervals will be also studied in pp collisions in order to
understand the small systems.
