Abstract
We study the double parton interaction process in collisions
between highly virtual pairs in the BFKL regime.
Explicit
expressions for the double parton distributions are obtained
both in the case
of direct coupling of the BFKL
pomerons to the
pair and in the case of triple pomeron
interaction.
