How the relation e^2/4pi = 1/137 may be obtained in the framework of Quantum Electrodynamics
G. Japaridze
In this pedagogical note it is demonstrated how the numeric value of fine structure constant may be established by comparing results following from the calculations in the framewor…
Universality of the rho-meson coupling in effective field theory
D. Djukanovic, M. R. Schindler, J. Gegelia +2
It is shown that both the universal coupling of the rho-meson and the Kawarabayashi-Suzuki-Riadzuddin-Fayyazuddin expression for the magnitude of its coupling constant follow from…
Power counting in relativistic baryon chiral perturbation theory
T. Fuchs, J. Gegelia, G. Japaridze +1
We consider a renormalization scheme for relativistic baryon chiral perturbation theory which provides a simple and consistent power counting for renormalized diagrams. As an appli…
Renormalization of relativistic baryon chiral perturbation theory and power counting
T. Fuchs, J. Gegelia, G. Japaridze +1
We discuss a renormalization scheme for relativistic baryon chiral perturbation theory which provides a simple and consistent power counting for renormalized diagrams. The method i…
On the Gauge Invariance of the Z-Boson Mass
J. Gegelia, G. Japaridze, A. Tkabladze +2
The different schemes for the definition of the Z boson mass are analyzed. It is shown that the scheme, defining the mass as pole of the real part of the Z boson propagator and the…
Color Octet Contribution to J/psi Photoproduction Asymmetries
George Japaridze, Wolf-Dieter Nowak, Avto Tkabladze
We investigate photoproduction asymmetries in the framework of the NRQCD factorization approach. It is shown that the color octet contribution leads to large uncertainties in…
