Semi-Analytical Approach to Four-Fermion Production in $e^+ e^-$ Annihilation

A study of the semi-analytical approach to four-fermion production in $e^+ e^-$ annihilation is presented. We classify all possible four-fermion final states and present results of new calculations for the `basic' processes with the $WW,ZZ$, and $ZH$ off-shell production together with some examples of `background' processes. The Initial State Radiative corrections are included for the basic processes. Several numerical examples are given in the energy range from LEP2 up to $\sqrt{s}=1$ TeV.

Semi-Analytical Approach to Higgs Production at LEP 2

The cross-section for the reaction $e^+e^- \rightarrow b\bar{b}μ^+μ^-$ is calculated with a semi-analytical integration of the phase space. Compact formulae are obtained for the total cross section and for invariant mass distributions of the $μ^+μ^-$ and $b\bar{b}$ pairs. The background diagrams to $ZH$ production yield analytically cumbersome but numerically small contributions. The numerical results are compared with those from a Monte Carlo approach.

Radiative Correction Schemes in Deep Inelastic Muon Scattering

A description and a detailed comparison of the Mo and Tsai and the Dubna radiative correction schemes is presented. Numerical comparisons made in the kinematical region of the NMC high energy deep inelastic electroproduction experiment are discussed. An overall agreement between the two approaches in the region of low $x$ and high $y$, where the radiative corrections are largest, is better than 2$\%$.
