Abstract

The gluon distribution (Formula presented) unintegrated over the transverse momentum (Formula presented) of the gluon, satisfies the angular-ordered CCFM equation which interlocks the dependence on the scale (Formula presented) with the scale (Formula presented) of the probe. We show how, to leading logarithmic accuracy, the equation can be simplified to a single-scale problem. In particular we demonstrate how to determine the two-scale unintegrated distribution (Formula presented) from knowledge of the integrated gluon obtained from a unified scheme embodying both BFKL (Formula presented) and DGLAP (Formula presented) evolution.
