The running of the electromagnetic coupling alpha in small-angle Bhabha scattering [PDF]

open access: yes, 2004
A method to determine the running of alpha from a measurement of small-angle Bhabha scattering is proposed and worked out. The method is suited to high statistics experiments at e+e- colliders, which are equipped with luminometers in the appropriate ...

Second Order Gauge Theory

open access: yes, 2007
A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength $G=\partial F+fAF$ arises besides the one of the first order treatment, $F=\partial A-\partial A+fAA$.

W-propagator corrections to muon and tau leptonic decays

open access: yes, 2013
We derive the corrections induced by the W-boson propagator to the differential rates of the leptonic decay of a polarized muon and tau lepton. Results are presented both for decays inclusive of inner bremsstrahlung as well as for radiative ones, when a ...

Non-perturbative solutions in the electro-weak theory with $\bar t t$ condensate and the $t$-quark mass

open access: yes, 2011
We apply Bogoliubov compensation principle to the gauge electro-weak interaction to demonstrate a spontaneous generation of anomalous three-boson gauge invariant effective interaction.

Hadronic Cross Sections in Electron-Positron Annihilation with Tagged Photon [PDF]

open access: yes, 1998
Events with tagged photons in the process of electron-positron annihilation into hadrons are considered. The initial state radiation is suggested to scan the hadronic cross section with the energy. QED radiative corrections are taken into account.

Practical and Efficient Synthesis of (E)-α,β-Unsaturated Amides Incorporating α-Aminophosphonates via the Horner–Wadsworth–Emmons Reaction

open access: yesMolecules
An efficient and practical procedure for the synthesis of (E)-α,β-unsaturated amides incorporating α-aminophosphonates, derived from readily accessible phosphonoacetamides, via the Horner–Wadsworth–Emmons (HWE) reaction was developed.

On relativization of the Sommerfeld-Gamow-Sakharov factor

open access: yes, 2011
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 singularity in radiative corrections at the threshold.

Von Neumann's Quantization of General Relativity

open access: yes, 2016
Von Neumann's procedure is applied for quantization of General Relativity. We quantize the initial data of dynamical variables at the Planck epoch, where the Hubble parameter coincides with the Planck mass.

Analytic Invariant Charge in QCD

open access: yes, 2003
This paper gives an overview of recently developed model for the QCD analytic invariant charge. Its underlying idea is to bring the analyticity condition, which follows from the general principles of local Quantum Field Theory, in perturbative approach ...

Deep Inelastic Scattering with Tagged Initial State Radiation: Complete O(alpha) leptonic QED Corrections

open access: yes, 2001
In this paper we extend the calculation of the QED corrections to deep inelastic lepton-proton scattering with a tagged photon, taking into account the full corrections on the lepton side.
