EXPERIMENTAL IDENTIFICATION OF QUARK AND GLUON JETS

With increasing luminosities at the LHC, the jet-studies become more accessible. With rising statistics and excellent detector capabilities, possibility emerges to identify jets as quarks or gluons to study and understand how differences in their fragmentation properties influence final particle spectra. We propose a method to separate jets into quark-like and gluon-like samples which can be performed directly on data without the necessity to rely on Monte Carlo. We study the fragmentation of the selected jets and compare to reference samples of quarks and gluons.
