16. Anomalous three gauge boson couplings in e+e−→ W+W−and “optimal” strategies for their measurement

Author

Diehl, M. and Nachtmann, O.

Abstract

We discuss how to measure anomalousWWZ- andWWγ-couplings with minimal statistical error using integrated observables, without having to assume that the anomalous couplings are small. We propose a parametrisation of these couplings which is well suited for the extraction of both single and many parameters, and which leads to a very simple form of the integrated cross section, from which additional information on the couplings can be obtained.

17. Open charm production in diffractive ep collisions

Author

Diehl, M.

Abstract

The cross section for the diffractive reactionγ + p → cc + pwith a real or virtual photon is calculated in the nonperturbative two-gluon exchange model of Landshoff and Nachtmann. Numerical predictions are given for cross sections and spectra at typical HERA values of c.m. energy and photon virtuality. The contribution of charm to the diffractive structure function is evaluated and found to be rather small in the model, and the ratio between the production rates for bb and cc is tiny.
