On the scale hierarchy in radiative symmetry breaking
A. B. Arbuzov, U. E. Voznaya, T. V. Kopylova
The emergence of a scale hierarchy in the case of spontaneous radiative breaking of conformal symmetry is discussed using the example of a simple quantum field theory model. The Co…
Forward-backward asymmetry in annihilation into pions or kaons revisited
A. B. Arbuzov, T. V. Kopylova, G. A. Seilkhanova
Forward-backward (charge) asymmetry in the processes of annihilation into a pair of charged pseudoscalar mesons is recalculated in the one-loop approximation. The exact de…
On spin asymmetry in muon and tau decays
A. B. Arbuzov, T. V. Kopylova, I. K. Sklyarov
The angular asymmetry in decays of polarized muons and tau leptons is discussed. Both the standard Fermi model and the general parameterization via Michel parameters are cons…
Michel parameters in radiative muon decay
A. B. Arbuzov, T. V. Kopylova
Radiative muon and tau lepton decays are described within the model-independent approach with the help of generalized Michel parameters. The exact dependence on charged lepton mass…
On higher order radiative corrections to elastic electron-proton scattering
A. B. Arbuzov, T. V. Kopylova
QED radiative corrections to elastic electron-proton scattering at low energies are discussed. Corrections to the electron line and effects due to vacuum polarization are computed.…
On a general way of two-particle problem reduction
A. B. Arbuzov, T. V. Kopylova, A. B. Zhunisbayev
The problem of the description of two interacting particles is considered. It is shown that it can be reduced to the description of one particle in an external static potential eve…
Off-mass-shell muon anomalous magnetic moment
A. B. Arbuzov, T. V. Kopylova
Interaction of charged leptons with photons is considered for the case when one of the lepton legs is off the mass shell. The effect due to off-mass-shell shift in the anomalous ma…
On relativization of the Sommerfeld-Gamow-Sakharov factor
Andrej B. Arbuzov, Tatiana V. Kopylova
The Sommerfeld-Gamow-Sakharov factor is considered for the general case of arbitrary masses and energies. It is shown that the scalar triangular one-loop diagram gives the Coulomb…
