Inclusive Jet Cross Section in Early LHC Data using the ATLAS Inner Detector

We present a method to study the emergence of low-momentum hadronic jets from soft proton-proton collisions with the ATLAS experiment at the Large Hadron Collider at CERN. The jets are reconstructed using tracks from the ATLAS Inner Detector. The track-based measurement will provide an independent check of calorimeter-based jet studies, and will allow the study of lower-momentum jets. This jet cross-section measurement, at the LHC's previously-unexplored energies, will provide new tests of quantum chromodynamics. We report on studies with Monte Carlo-simulated events for an analysis planned for early, low-luminosity data collected with a minimum bias trigger.
