Searching the Color Glass Condensate Through Suppression
M. A. Betemps, M. B. Gay Ducati
In this work the rapidity and transverse momentum dependence of the nuclear modification ratio is evaluated for the dilepton production at RHIC and LHC, using the Color Glass Conde…
Dynamical gluon mass and elastic scattering
M. B. Gay Ducati, W. K. Sauter
The application of a modified gluon propagator and an infrared frozen running co upling constant in the description of the proton-proton elastic scattering is in vestigated. The mo…
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…
Improved mapping of ccbar onto charmonium states
C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman
We discuss the relative rates of different charmonium states and introduce an improved model for mapping the continuous ccbar mass spectrum on the physical charmonium resonances.
Soft and hard QCD in charmonium production
C. Brenner Mariotto, M. B. Gay Ducati, G. Ingelman
Hard and soft QCD dynamics are both important in charmonium hadroproduction, as presented here through a next-to-leading order QCD matrix element calculation combined with the colo…
