Measurements of the inclusive jet cross section and jet fragmentation in pp collisions with the ALICE experiment at the LHC

Understand

Jet reconstruction and jet fragmentation variables provide important information to study the interaction between hard scattered partons and the Quark-Gluon Plasma.

• This paper presents the measurement of the inclusive cross section for fully reconstructed jets in pp collisions at sqrt(s) = 2.76 TeV, which provides an essential reference for jet measurements in Pb-Pb collisions at the same sqrt(s_NN).
• In addition, we report jet fragmentation measurements for charged particle jets in pp collisions at sqrt(s) = 7 TeV.
• These measurements utilize the ALICE central barrel tracking system to detect charged particles with good efficiency above 150 MeV/c, together with the Electromagnetic Calorimeter (EMCal).
