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.…
Scattering amplitude in QCD: summing large Pomeron loops
Eugene Levin
In this paper we show that the sum of enhanced BFKL Pomeron loop diagrams generates the scattering amplitude, which turns out to be much smaller, than in the case of deep inelastic…
Gluon structure function for deeply inelastic scattering with nucleus in QCD
M. B. Gay Ducati, Alvaro L. Ayala, E. Levin
In this talk we present the first calculation of the gluon structure function for nucleus in QCD. We discuss the Glauber formula for the gluon structure function and the violation…
