Abstract
The AGE equation includes all multiple pomeron exchanges in the double loga rithmic approximation (DLA) limit, leading to a unitarized gluon distributi on in the small x regime. This equation was originally obtained using the G lauber-Mueller approach. We demonstrate in this paper that the AGL equation and, consequently, the GLR equation, can also be obtained from the dipole picture in the double logarithmic limit, using an evolution equation, recen tly proposed, which includes all multiple pomeron exchanges in the leading logarithmic approximation. Our conclusion is that the AGL equation is a goo d candidate for a unitarized evolution equation at small x in the DLA limit . (C) 1999 Elsevier Science B.V. All rights reserved.
