For both models we have considered various coupling strengths in the scalar diquark channel, showing that different low-temperature quark matter phases can occur at

The treatment of J / ψ electroproduction exhibits clearly the factorization property [3], with all Q 2 dependence of the am- plitudes and cross sections contained in the strength of

We present results on the quark and gluon polarization in the nucleon obtained in a combined next to leading order analysis to the available inclusive and semi-inclusive polarized

The collision between the jet, emitted by the compact object, and the dense equatorial disk of the companion massive star is responsible for the gamma-ray production.. Gamma-rays

its QCD evolution has been recently computed [7], which im- proves the high Q 2 data description. Moreover, we present the recent results on the experimental extraction of the

First, the dilepton production in the color dipole approach is investigated, studing perturbative unitarity corrections to the dipole cross section and its consequence in the

In the AdS/CFT correspondence Wilson loops for a heavy quark anti-quark pair in the conformal gauge theory can be calculated from a static string in the AdS space[44, 45]..

Still, if we assume that the presence of this new effect is not strong enough to break adiabaticity of solar neutrino evolution, the combined analysis of the so- lar [2–7] and
