METHODOLOGY FOR MEASURING GLUON JET FRACTION AND CHARACTERISTICS OF QUARK AND GLUON JETS IN HADRON-HADRON COLLISIONS

摘要

The difference in properties of jets initiated by quarks and gluons as a result of pp 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 makes it possible to measure various characteristics of quark and gluon jets. The technique of such measurements for modern hadron colliders is discussed.
