Description

We discuss the new derivation of the linear but with complicated kernel and non-homogeneous evolution equations for the cross sections of productions of $n$-cut Balitsky-Fadin-Kuraev-Lipatov (BFKL) Pomerons in the final states of high energy DIS on a nucleus, resumming all multiple rescatterings and all leading logarithms of energy. These equations coincide with the equations that have been derived using the Abramovsky, Gribov and Kancheli (AGK) cutting rules but based on the dipole approach to QCD. In the second part of the talk we discuss approximate analytical solutions for the equations in the small-$n$ and large-$n$ approaches and compute the multiplicity distribution for the produced gluons, their probability to be found and the entropy content of the multiplicity distribution for the large-$n$ solution at high values of the geometric scaling variable $z=\ln(r^2 Q_s^2)$.
