Adler function in the analytic approach to QCD
A. V. Nesterenko
The low energy behavior of the Adler function D(Q^2) is studied by employing recently derived integral representation for the latter. This representation embodies the nonperturbati…
QCD coupling below 1 GeV from quarkonium spectrum
M. Baldicchi, A. V. Nesterenko, G. M. Prosperi +1
In this paper we extend the work synthetically presented in Ref.[1] and give theoretical details and complete tables of numerical results. We exploit calculations within a Bethe-Sa…
Bound state approach to the QCD coupling at low energy scales
M. Baldicchi, A. V. Nesterenko, G. M. Prosperi +2
We exploit theoretical results on the meson spectrum within the framework of a Bethe-Salpeter (BS) formalism adjusted for QCD, in order to extract an ``experimental'' coupling α_s^…
Infrared enhanced analytic coupling and chiral symmetry breaking in QCD
A. C. Aguilar, A. V. Nesterenko, J. Papavassiliou
We study the impact on chiral symmetry breaking of a recently developed model for the QCD analytic invariant charge. This charge contains no adjustable parameters, other than the Q…
The massive analytic invariant charge in QCD
A. V. Nesterenko, J. Papavassiliou
The low energy behavior of a recently proposed model for the massive analytic running coupling of QCD is studied. This running coupling has no unphysical singularities, and in the…
The QCD analytic running coupling and chiral symmetry breaking
A. V. Nesterenko, J. Papavassiliou
We study the dependence on the pion mass of the QCD effective charge by employing the dispersion relations for the Adler D function. This new massive analytic running coupling is c…
