Methodology for Measuring Gluon Jet Fraction and Characteristics of Quark and Gluon Jets in Hadron-Hadron Collisions

Abstract

The difference in properties of jets initiated by quarks and gluons as a result of hadron–hadron collisions, opens up the possibility of their recognition. Special quark-gluon discriminators of jets are built for this purpose. This paper discusses methods for measuring the fractions of quark and gluon jets in jet sample using the quark-gluon jet discriminator. This opens up the possibility of measuring various characteristics of quark and gluon jets. The technique of such measurements for modern hadron colliders is discussed.
