Lucha, ¿contra qué pobreza? [PDF]
Economia, 2005 En este artículo presentaremos una de las génesis de lo que actualmente es, para muchos, lo más original de la política social: la lucha contra la pobreza. Para ello recurriremos principalmente a un esfuerzo pionero de reorientación de dicha lucha que se presentó en un folleto de la Cámara de Comercio de los EEUU, editado en 1965, con el título The ...

Isospin Breaking in Heavy-Meson Decay Constants
, 2017 Evaluation of Borelized QCD sum rules in the so-called local-duality limit of infinitely large Borel mass parameter provides an alternate route for extraction of the dependence of the decay constants of heavy-light mesons on the mass $m_q$ of the ...

Local-duality QCD sum rule for the pion elastic form factor
, 2010 This work presents the results of our analysis of the accuracy of the pion form factor derived from the local-duality version of QCD sum rules.Comment: Presented at the International Conference "Quark Confinement and the Hadron Spectrum IX", August ...

Analytic Quest for Confining Interaction Kernels in Instantaneous Bethe-Salpeter Equations
, 2010 The Salpeter equation, a standard tool in hadron physics, constitutes a well-defined three-dimensional approximation to the Bethe-Salpeter formalism for the description of bound states within quantum field theories. However, if confinement is implemented

Instantaneous Bethe-Salpeter Approach to Pseudoscalar Mesons
, 2013 Light pseudoscalar mesons are Janus-type particles: Within quantum chromodynamics, they must be described as bound states of its fundamental degrees of freedom and as the (pseudo-) Goldstone bosons of its spontaneously broken chiral symmetry.

Local-duality QCD sum rules for strong isospin breaking in the decay constants of heavy-light mesons
, 2018 We discuss the leptonic decay constants of heavy--light mesons by means of Borel QCD sum~rules in the local-duality (LD) limit of infinitely large Borel mass parameter.

Quark-Hadron Duality and Effective Continuum Thresholds in Dispersive Sum Rules
, 2010 A novel procedure for extracting hadron characteristics from QCD sum rules, based on effective continuum thresholds (necessary for the implementation of quark-hadron duality) which may depend on the involved momenta and on the Borel parameter(s), enables
