The Pomeron as a Finite Sum of Gluon Ladder
R. Fiore, L. L. Jenkovszky, A. Lengyel +2
A model for the Pomeron at t=0 is suggested. It is based on the idea of a finite sum of ladder diagrams in QCD. Accordingly, the number of s-channel gluon rungs and correspondingly…
Analytic Model of a Regge Trajectory in the Space-like and Time-like Regions
R. Fiore, L. L. Jenkovszky, V. Magas +2
A model for a Regge trajectory compatible with the threshold behavior required by unitarity and asymptotics in agreement with Mandelstam analyticity is analyzed and confronted with…
Hadron Diffraction Dissociation and the Triple Pomeron Vertex
R. Fiore, L. L. Jenkovszky, F. Paccanoni
Hadron diffraction dissociation is considered in the dipole Pomeron model where the Pomeron is represented by a double pole in the J-plane. We find that unitarity is satisfied with…
Approximate solution of the BFKL equation applicable at HERA
P. Desgrolard, L. Jenkovszky, F. Paccanoni
We suggest a formula interpolating between the known asymptotic regimes of the BFKL equation as the approximate solution of that equation. The parameters appearing in this interpol…
Pomeron Non Factorization in Diffractive Scattering at HERA
R. Fiore, A. Flachi, L. L. Jenkovszky +1
Pomeron non factorization for the diffractive scattering is considered and an analysis of experimental data is performed with different cuts in the momentum fraction . The resul…
Non-factorizable Contributions to the Large Rapidity Gap at HERA
R. Fiore, L. L Jenkovszky, F. Paccanoni +1
The large rapidity gap events from HERA are analyzed within a model containing a pomeron and an -reggeon contribution. The choice for the pomeron contribution is based on the Do…
