The High Density Effects in Heavy Quark Production at pA Colliders
A. L. Ayala Filho, V. P. Goncalves
In this paper we investigate the role of the high density effects in the heavy quark production cross section in processes at RHIC and LHC. We use, as initial condition, a glu…
The improved nuclear parton distributions
A. L. Ayala Filho, V. P. Goncalves
In this paper we propose an improvement of the EKS nuclear parton distributions for the small x region of high energy processes, where the perturbative high parton density effects…
On the Determination of Small x Shadowing Corrections at HERA
A. Ayala, M. B. Gay Ducati, Victor P. Goncalves
The recent data can be described using the DGLAP evolution equations with an appropriate choice of input distributions and the choice of the starting scale for the evol…
Scaling violation and shadowing corrections at HERA
A. L. Ayala Filho, M. B. Gay Ducati, E. M. Levin
We study the value of shadowing corrections (SC) in HERA kinematic region in Glauber - Mueller approach. Since the Glauber - Mueller approach was proven in perturbative QCD in the…
Parton Densities in a Nucleon
A. L. Ayala Filho, M. B. Gay Ducati, E. M. Levin
In this paper we re-analyse the situation with the shadowing corrections (SC) in QCD for the proton deep inelastic structure functions. We reconsider the Glauber - Mueller approach…
QCD evolution of the gluon density in a nucleus
A. L. Ayala, M. B. Gay Ducati, E. M. Levin
The Glauber approach to the gluon density in a nucleus, suggested by A. Mueller, is developed and studied in detail. Using the GRV parameterization for the gluon density in a nucle…
