Chiral condensates from tau decay: a critical reappraisal
Jose Bordes, Cesareo A. Dominguez, Jose Penarrocha +1
The saturation of QCD chiral sum rules is reanalyzed in view of the new and complete analysis of the ALEPH experimental data on the difference between vector and axial-vector corre…

B and B_S decay constants from moments of Finite Energy Sum Rules in QCD
F. Bodi-Esteban, J. Bordes, J. Penarrocha
We use an appropriate combination of moments of finite energy sum rules in QCD in order to compute the B_q-meson decays constants f_B and f_{B_s}.We perform the calculation using a…

Bottom quark mass and QCD duality
J. Bordes, J. Penarrocha, K. Schilcher
The mass of the bottom quark is analyzed in the context of QCD finite energy sum rules. In contrast to the conventional approach, we use a large momentum expansion of the QCD corre…
