The O (αs) corrections to the vacuum polarization tensor of the gauge bosons are presented for both light and heavy quark flavours in the standard model of electroweak interactions on the basis of a running coupling constant αs. The influence of ϒ

A Monte Carlo program simulating fermion pair production is presented. It features multiphoton bremsstrahlung out of the initial state beams. The contributions from soft photons are summed rigorously up to an infinite order using the Yennie-Frautschi

Bhabha scattering in the energy region around the Z0 boson has been studied. The calculation is performed in the standard electroweak theory and contains all O (α) radiative corrections, i.e. virtual, soft photon and hard photon corrections. Some re

An event generator for radiative Bhabha scattering with missing e+ and/or e- is developed in electroweak theory. The program can generate events of three configurations, in which single γ, single e and eγ are observed.

This lecture reviews the main advances of high energy physics in the last decade, a period during which a number of major developments took place in our knowledge of the constituents of matter and of the basic laws of interaction. After a brief histo

We describe an extension of the SOFTSUSY spectrum calculator to include two-loop supersymmetric QCD (SUSYQCD) corrections of order O ( α s 2 ) to gluino and squark pole masses, either in the minimal supersymmetric standard model (MSSM) or the next-t
