Singular structure of the QED effective action
Biruniy Fayzullaev
The equations for the QED effective action derived in \cite{fm} are considered using singular perturbation theory. The effective action is divided into regular and singular (in cou…
Effective action and vacuum expectations in nonlinear model
B. A. Fayzullaev
The equations for effective action for nonlinear model are derived using DeWitt method in two forms - for generator of vertex parts and for generator of weakly connected pa…
On the Hamiltonian form of the Einstein equations for gravitational field
Biruniy Fayzullaev
It is shown that Einstein gravitational equations and canonical equations following from the Dirac-Schwinger Hamiltonian in the Faddeev variables coincide. For proving of this at f…
Knot soliton in Weinberg-Salam model
B. A. Fayzullaev, M. M. Musakhanov, D. G. Pak +1
We study numerically the topological knot solution suggested recently in the Weinberg-Salam model. Applying the SU(2) gauge invariant Abelian projection we demonstrate that the res…
The s-wave pi d scattering length from pi d atom using effective field theory
B. F. Irgaziev, B. A. Fayzullaev
The pi- d atom strong energy-level shift in the 1s state is derived by using the effective field theory. Taking into account the large value of radius of pionic deuterium and short…
