Jet reconstruction in hadronic collisions by Gaussian filtering
Abstract
A new algorithm for jet finding in hadronic collisions is presented. The algorithm, based on a Gaussian filter in (η,φ), is specifically intended for use in heavy ion collisions and/or for detectors with limited acceptance. The performance of the algorithm is compared to two conventional algorithms, a seedless cone algorithm and a k algorithm, for Pythia simulated di-jet events in s = 200 GeV p + p collisions with 4 GeV/c Q2 16 GeV/c. The Gaussian filter is found to perform as well as, and in some instances better than, the conventional algorithms.
