This new massive analytic running coupling is compared to the effective coupling saturated by the dynamically generated gluon mass. A qualitative picture of the possible impact of the former coupling on the chiral symmetry breaking is presented.Talk given at 11th International QCD Conference (QCD 04), 5 - 10 July 2004, Montpellier, France; 4 pages, 4 figuresHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
