Description
Jets are produced by highly virtual quarks and gluons that emerge from initial hard scattering processes and are an important probe of the QCD evolution of the collision. Jet measurements in small systems such as pp are important in order to provide constraints on the parton distribution functions (PDFs) of the proton and the strong coupling constant $\alpha_{s}$. They also test pQCD calculations and the fragmentation of partons into hadrons. They can also be used as a reference for more complex systems, such as p--Pb and Pb--Pb collisions, where cold nuclear matter effects and a strongly-interacting medium play a role. While jet cross-section measurements provide a test for pQCD calculations and also help to constrain QCD-based MC models, jet cross-section ratios are very good tools to test the inner structure of jets. Measuring jet cross-section ratios at different jet resolution parameters and at different center of mass energies tests the universalities of fragmentation functions. In this poster we present jet cross-section measurements at different jet resolution and collision centre-of-mass energies. This work extends previous jet studies at ALICE by taking a first look at the high statistics and precision measurements of fully reconstructed jets (full jets reconstructed from charged-particle tracks and neutral constituents) with Run 3 data.
