Gluon condensate in charmonium sum rules for the axial-vector current
A. Samsonov
The charmonium sum rules for the axial-vector current are considered. The three-loop perturbative corrections, operators up to 8 dimension and perturbative corrections to the lowes…
Magnetic moment of the rho-meson in QCD sum rules: perturbative corrections
A. Samsonov
The magnetic moment of the rho-meson is calculated in the framework of QCD sum rules in external fields. Perturbative corrections are taken into account. Bare loop calculations (pa…
Correlator of Topological Charge Densities in Instanton Model in QCD
B. L. Ioffe, A. V. Samsonov
The QCD sum rule for the correlator of topological charge densities and related to it longitudinal part of the correlator of singlet axial currents is considered in the framework o…
Decay constant of eta-meson from QCD sum rule
A. V. Samsonov
Decay constant of eta-meson f is calculated on the basis of the QCD sum rule method. An instanton contribution is taken into account. The result is f = 0.17 GeV.
Forward scattering amplitude of the virtual longitudinal photon in QED
A. V. Samsonov
Forward scattering amplitude of the virtual longitudinal photon at zero energy on electron in QED in the limit of small photon virtualities is calculated. The first radiation corre…
