Investigating the role of average color dipole size in BFKL Pomeron phenomenology

A. I. Lengyel, M. V. T. Machado

Based on the QCD dipole picture of the BFKL Pomeron, we investigate the role played by the saturation scale, Q_{sat}, in obtaining physical values for the affective strong coupling…

Deeply Virtual Compton Scattering in the Saturation Approach

Laurent Favart, Magno V. T. Machado

We summarize here our investigations on the deeply virtual Compton scattering (DVCS) in the color dipole approach, implementing the dipole cross section through the saturation mode…

Dilepton Transverse Momentum in the Color Dipole Approach

M. A. Betemps, M. B. Gay Ducati, M. V. T. Machado +1

We investigate the Drell-Yan transverse momentum distribution in the framework of the color dipole approach. Special attention is paid to parton saturation effects at high energies…

Aspects of the Heavy-Quark Photoproduction in the Semihard Approach

C. Brenner Mariotto, M. B. Gay Ducati, M. V. T. Machado

In this contribution we report on the calculations of heavy-quark photoproduction using the semihard approach, emphasizing the results obtained with the phenomenological saturation…

The Diffractive Logarithmic Slope and the Saturation Phenomena

M. B. Gay Ducati, V. P. Gonçalves, M. V. T. Machado

The logarithmic slope of the diffractive structure function is a potential observable scanning the hard and soft contributions in diffraction, allowing to disentangle the QCD dynam…

Hard and Soft Contributions in Diffraction

M. B. Gay Ducati, V. P. Goncalves, M. V. T. Machado

We report our calculations on the logarithmic slope of the diffractive structure function F_2^D considering distinct approaches coming from both the pQCD and the Regge descriptions…
