Calculation of Particle Decay Times in the Standard Model

This paper presents traditional and new methods and results for calculation of decay times of particles in the Standard Model. In chapters 1 and 2 the phenomenological and the theoretical knowledge of the decays is presented, based on the literature. In chapters 4 and 5 the interaction energy (mass-energy mX of the mediating boson in the Feynman diagram) is introduced and a characterization of the decays, based on particle type, isospin, and interaction energy, is presented. In chapter 6 the calculation model and the calculation results of selected typical decays are discussed.
