Abstract: | We present the first measurement of reconstructed jets in ultra-relativistic heavy ion collisions. Utilizing the large coverage
of the STAR Time Projection Chamber and Electromagnetic Calorimeter, we apply several modern jet reconstruction algorithms
and background subtraction techniques and explore their systematic uncertainties in heavy ion events. The differential energy
spectrum for inclusive jet production in central Au+Au collisions at
is presented. In order to assess the jet reconstruction biases, this spectrum is compared with the jet cross section measured
in
GeV p+p collisions scaled by the number of binary N–N collisions to account for nuclear geometric effects. |
