Generalized distribution amplitudes: new tools to study hadrons' structure and interactions
R. Fiore, A. Flachi, L. L. Jenkovszky +2
A non-perturbative approach to Generalized Parton Distributions, and to Deeply Virtual Compton Scattering in particular, based on off mass shell extension of dual amplitudes with M…
Explicit model realizing parton-hadron duality
R. Fiore, A. Flachi, L. L. Jenkovszky +2
An explicit model realizing parton-hadron duality and fitting the data is suggested. Complex nonlinear Regge trajectories are important ingredients of the model. The inclusion of $…
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…
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…
