Small-Angle Bhabha Scattering at LEP1. Analytical Results for Wide-Narrow Angular Acceptance
A. B. Arbuzov, G. I. Gach, V. Yu. Gontchar +3
Analytical formulae for small-angle Bhabha scattering cross-section at LEP1 are given for the case of wide-narrow angular acceptance. Inclusive and calorimeter event selections are…
Small angle Bhabha scattering at LEP1. Wide-narrow angular acceptance
N. P. Merenkov
Analytical method is applied for description of the small angle Bhabha scattering at LEP1. Inclusive event selection for asymmetrical wide-narrow circular detectors is considered.…
Generalized action principle and extrinsic geometry for N=1 superparticle
Igor A. Bandos, Alexei Yu. Nurmagambetov
It is proposed the generalized action functional for N=1 superparticle in D=3,4,6 and 10 space-time dimensions. The superfield geometric approach equations describing superparticle…
Emission of Two Hard Photons in Large-Angle Bhabha Scattering
A. B. Arbuzov, V. A. Astakhov, E. A. Kuraev +3
A closed expression for the differential cross section of the large-angle Bhabha scattering which explicitly takes into account the leading and next-to-leading contributi…
On the BRST Quantization of the Massless Bosonic Particle in Twistor-Like Formulation
Igor Bandos, Alexey Maznytsia, Igor Rudychev +1
We study some features of bosonic particle path-integral quantization in a twistor-like approach by use of the BRST-BFV quantization prescription. In the course of the Hamiltonian…
Small-Angle Bhabha Scattering
A. B. Arbuzov, V. S. Fadin, E. A. Kuraev +3
We present the calculation of the elastic and inelastic high--energy small--angle electron--positron scattering with a {\it per mille} accuracy. PACS numbers 12.15.Lk, 12.20.--m, 1…
