QCD phenomenology with infrared finite SDE solutions
(2009-12-01)
Recent progress in the solution of Schwinger-Dyson equations (SDE), as well as lattice simulation of pure glue QCD, indicate that the gluon propagator and coupling constant are infrared (IR) finite. We discuss how this ...

Scalar coupling evolution in a non-perturbative QCD resummation scheme
(2015-07-01)
We compute the Standard Model scalar coupling (λ) evolution in a particular QCD resummation scheme, where the QCD coupling becomes infrared finite due to the presence of a dynamically generated gluon mass, leading to the ...
QCD effective charge and the structure function F-2 at small-x
(Elsevier B.V., 2011-03-28)
We study infrared contributions to the QCD description of the HERA data on the structure function F-2 within the generalized DAS approximation. We argue that this approximation is a natural one and consistent with the ...
Non-perturbative RPA-method implemented in the Coulomb gauge QCD Hamiltonian: From quarks and gluons to baryons and mesons
(Springer, 2018-02)
Starting from an algebraic model based on the QCD-Hamiltonian and previously applied to study meson states, we have developed an extension of it in order to explore the structure of baryon states. In developing our approach ...

QCD sum rule calculation for the charmonium-like structures in the J/psi phi and J/psi omega invariant mass spectra
(ELSEVIER SCIENCE BV, 2011)
Using the QCD sum rules we test if the charmonium-like structure Y(4274), observed in the J/psi phi invariant mass spectrum, can be described with a D(s)(D) over bar (s0)(2317)+ h.c. molecular current with J(PC) = 0(-+). ...
Relation between Tcc,bb and Xc,b from QCD.
(W. HaxtonHolanda do Norte, 2011-07-28)
We have studied, using double ratio of QCD (spectral) sum rules, the ratio between the masses of Tcc and
X(3872) assuming that they are respectively described by the D−D∗ and D− ¯D∗ molecular currents. We
found (within ...
