Description

Measurement of the characteristics of quark (q) and gluon (g) jets begins with measuring the q/g-jet fractions in jet sample. To extract the q/g-jet characteristics, two jet samples with significantly different q/g-jet fractions are required. In a real experiment, jet samples differ in kinematics, which leads to the fact that q/g-jet characteristics depend on jet sample. Formulas for kinematic corrections to q/g-jet characteristics are obtained. The technique is illustrated on data from the CMS.
