Keywords:
Elementary particle physics, QED, Electron-positron collision,
Radiative return, Anomalous three gauge boson couplings.
Programming language used: Fortran
Nature of physical problem:
Precise cross sections of hard photon productions with missing energy.
Study of anomalous triple-gauge-boson couplings at LEP-2.
Method of solution:
The exact matrix elements of single- and double-photon emission,
generated by the GRACE system, are convoluted with the QED parton shower
(QEDPS) to deal with the initial state radiations (ISR).
Restrictions:
Convergency of the integration may be bad when inappropriate
experimental cuts are applied.
Typical running time:
1 hour.
Unusual features:
When errors of the integration are greater than several percent even
with more than 10 M sampling points, please contact the authors.
