Abstract
The triple pomeron interaction is studied in the perturbative approach of BFKL-Bartels. At finite momentum transfers √−t the contribution factorizes in the standard manner with a triple-pomeron vertex proportional to 1/√−t, Att=0 the contribution is finite, although it grows faster with energy than for finitet and does not factorize.
