Dipole-dipole scattering at high energy in the Pomeron field theory with Braun Hamiltonian and beyond
Eugene Levin
In this paper we find that the scattering matrix for dipole-dipole interaction in the saturation region has the form: ${\cal S}^d_d \xrightarrow{z \,\gg\,1} \exp\Lb - C^d_d z^2\Rb…
Dipole-dipole scattering: summing large Pomeron loops in non-linear evolution with leading twist kernel
Eugene Levin
It is shown in this paper that the QCD equations for dipole density have the natural solution: the 'fan' diagrams of the Pomeron calculus. We found the dipole densities comparing t…
Summing large Pomeron loops in the saturation region: dipole-nucleus collision beyond nonlinear equations
Eugene Levin
In this paper we found the dipole-nucleus scattering amplitude at high energies by summing large Pomeron loops. It turns out that the energy dependence of this amplitude is the sam…
Particle production in the toy world: multiplicity distribution and entropy
Eugene Levin
In this paper we found the multiplicity distribution of the produced dipoles in the final state for dipole-dipole scattering in the zero dimension toy models. This distribution sho…
Summing large Pomeron loops in the saturation region: amplitude and multiplicity distributions for dipole-dipole scattering
Eugene Levin
In this paper we found the parton densities at high energies. Their expressions stems from our attempts to reconcile the exact solution to the Balitsky-Kovchegov (BK) equation, whi…
High energy scattering in the Unitary Toy Model
Alex Kovner, Eugene Levin, Michael Lublinsky
We continue exploring the Unitary Toy Model (UTM) as a playground for high energy collisions in QCD. Our new approach is based on the diagonalization of the evolution Hamiltonian.…
