The SVZ-Expansion and Beyond
Stephan Narison
I discuss the standard SVZ-expansion of the QCD two-point correlators in terms of the QCD vacuum condensates and beyond it due to a new unflavoured 1/Q^2-term (tachyonic gluon mass…
Heavy-light mesons in QCD
Stephan Narison
This talk summarizes the study of the dynamics of the heavy-light \bar Qq open charm and beauty mesons obtained in [1] using QCD spectral sum rules (QSSR) and motivated by the rece…
Fundamental Research and Developing Countries
Stephan Narison
In the first part of this report, I discuss the sociological role of fundamental research in Developing Countries (DC) and how to realize this program. In the second part, I give a…
New Evaluation of the QED Running Coupling and of the Muonium Hyperfine Splitting
Stephan Narison
We present a new independent evaluation of the hadronic and QCD contributions to the QED running coupling α(M_Z) and to the muonium hyperfine splitting ν. We obtain: Δα_{had}=2770(…
On the Quark and Gluon Substructure of the Sigma and other Scalar Mesons
Stephan Narison
Within the increasing experimental evidence of the existence of the I=0 scalar low mass and wide σmeson, we review the {\it first} analysis of its quark and gluon substructure from…
Running charm quark mass versus M_D and the D_(s) into μνdecay
Stephan Narison
I study (for the first time) the dependence of M_D and of the leptonic decay constant f_D on the variation of the running charm quark mass m_c(ν). I conclude that the present data…
