The small x behavior of the gluon structure function from total cross-sections
(2008-01-10)
Within a QCD-based eikonal model with a dynamical infrared gluon mass scale we discuss how the small x behavior of the gluon distribution function at moderate Q 2 is directly related to the rise of total hadronic cross-sections. ...
Bounds on the gluon mass from nucleon decay

A dynamical gluon mass solution in Mandelstam's approximation
(World Scientific Publ Co Pte Ltd, 2005-12-30)
We discuss the pure gauge Schwinger-Dyson equation for the gluon propagator in the Landau gauge within an approximation proposed by Mandelstam many years ago. We show that a dynamical gluon mass arises as a solution. This ...
The small x behavior of the gluon strucutre function from total cross-sections
(World Scientific Publ Co Pte Ltd, 2008-01-10)
Within a QCD-based eikonal model with a dynamical infrared gluon mass scale we discuss how the small x behavior of the gluon distribution function at moderate Q(2) is directly related to the rise of total hadronic ...
Phenomenology of infrared finite gluon propagator and coupling constant
(Sociedade Brasileira de Física, 2007-03-01)
We report on some recent solutions of the Dyson-Schwinger equations for the infrared behavior of the gluon propagator and coupling constant, discussing their differences and proposing that these different behaviors can be ...
Diffraction and an infrared finite gluon propagator
(Sociedade Brasileira de Física, 2007-03-01)
We discuss some phenomenological applications of an infrared finite gluon propagator characterized by a dynamically generated gluon mass. In particular we compute the effect of the dynamical gluon mass on pp and ${\bar{p}}p$ ...
Diffraction and an infrared finite gluon propagator
(Springer, 2007-03-01)
We discuss some phenomenological applications of an infrared finite gluon propagator characterized by a dynamically generated gluon mass. In particular we compute the effect of the dynamical gluon mass on pp and,pp diffractive ...
QCD chiral symmetry restoration with a large number of quarks in a model with a confining propagator and dynamically massive gluons
(Elsevier B.V., 2015-05-11)
Considering a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass, we verify that the chiral symmetry is ...
Multivacuum states in a fermionic gap equation with massive gluons and confinement
(World Scientific Publ Co Pte Ltd, 2015-05-10)
We study the nontrivial solutions of the Quantum Chromodynamics (QCD) fermionic gap equation (FGE) including the contribution of dynamically massive gluons and the confining propagator proposed by Cornwall. Without the ...
Influence of a dynamical gluon mass in the pp and (p)over-bar-p forward scattering
(American Physical Soc, 2005-08-01)
We compute the tree level cross section for gluon-gluon elastic scattering taking into account a dynamical gluon mass, and show that this mass scale is a natural regulator for this subprocess cross section. Using an eikonal ...
