Abstract: Direct measurement of jets in GeV Heavy Ion Collisions by STAR

Jet quenching measurements using leading particles and their correlations suffer from known biases, which can be removed using full jet reconstruction. In this talk, we present the systematic measurements of direct jet reconstruction in heavy ion collisions. Using the large coverage of the STAR TPC and EM Calorimeter, we apply several modern jet reconstruction algorithms and background subtraction techniques that are appropriate to heavy ion collisions. We explore their parameter spaces to determine systematic uncertainties. The first inclusive spectrum of high jets in GeV heavy ion collisions will be presented. We illustrate how the underlying background affects the reconstructed energy for various algorithms. In order to asses the jet reconstruction biases we compare the jet rates in heavy ion with the results of binary scaled p+p collisions.
