Analytic calculation of feynman amplitudes

Physics of Atomic Nuclei, 2003
A new method is proposed for calculating amplitudes of processes involving spin-1/2 fermions.The method is based on the use of the isotropic-vierbein vectors in Minkowski space and the basis spinors associated with them.The amplitudes for the electron -positron interaction processes e − e + → f ¯ f and e − e + → W − W + and the amplitude for one of the

Analytical calculation of the Elsasser integral

Journal of Applied Spectroscopy, 1973
?(2) b This formula served as the basis for the derivation of various precise analytical expressions for the Elsasser integral [2-4]. In [2] the solution was found in the form of a series which converges only for chz < 2. However, for large values of a the series converges poorly and, in order to calculate the integral," calculations must be made with ...

Influence of the Calculated Analyte Structure on the Quality of Theoretical ion Mobility Calculations

Proceedings of the 7th International Conference on Informatics, Environment, Energy and Applications, 2018
Ion mobility spectrometry is a well-known technique used to identify and analyze substances in environmental monitoring by their characteristic ion mobility. In typical scenarios, there is only insufficient information available regarding what substances will be present.

On the use of Analytical Theories in the Calculation of Precession-Nutation

Celestial Mechanics and Dynamical Astronomy, 1997
We present the use of the analytical solutions of the planets and of the Moon’s motion in the determination of the quantities which relate the barycentric and the geocentric coordinate systems and of the expressions of precession-nutation. The computation of the precession and nutation quantities are built with the analytical theories of the motion of ...
