We explain the concept of worldline Green functions on classes of multiloop graphs. The QED β – function and the 2-loop Euler-Heisenberg Lagrangian are discussed for illustration.

The system of two relativistic particles with einbein fields is quan-tized as a constrained system. A method of the introduction of the Newton–Wigner collective coordinate is discussed in presence of different gauge fixing conditions. Some arguments are involved in the favour of Lorents covariant gauge fixing conditions.

Results of complete tree level calculation of the single top and light Higgs production in the reaction γe −→ ν b b̄W at the Next Linear Collider are presented. In addition, the contributions of anomalous operators to the Wtb and WWH couplings are included into the complete 4-body consideration. The sensitivity for probing the structure of the couplings in a model independent way is analyzed.
