### Abstract

The gluon distribution f(x,k_{t}^{2},μ^{2}), unintegrated over the transverse momentum k_{t} of the gluon, satisfies the angular-ordered CCFM equation which interlocks the dependence on the scale k_{t} with the scale μ 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 f(x,k_{t}^{2},μ^{2}) from knowledge of the integrated gluon obtained from a unified scheme embodying both BFKL [log(1/x)] and DGLAP (log μ^{2}) evolution.

N2 - The gluon distribution f(x,kt2,μ2), unintegrated over the transverse momentum kt of the gluon, satisfies the angular-ordered CCFM equation which interlocks the dependence on the scale kt with the scale μ 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 f(x,kt2,μ2) from knowledge of the integrated gluon obtained from a unified scheme embodying both BFKL [log(1/x)] and DGLAP (log μ2) evolution.
