Nature of problem:
The process e+e- -> nunubar(etagamma) provides important observables, which are sensitive to parameters of the standard electroweak theory as well as possible effects of new physics. A Monte Carlo simulation of this process is necessary in order to evaluate the effects of QED bremsstrahlung and the experimental apparatus on the observables in question. Simultaneous control of the precise Standard Model predictions and contributions due to hypotethical new physics extensions is mandatory in such studies.
The Monte Carlo simulation of nunubaretagamma production is augmented by the calculation of weights incorporating effects due to the SM and anomalous WWgamma couplings. Calculation of these weights is performed in the GengLib library. Powerful reweighting methods and fitting with the help of a Monte Carlo sample are thus possible for experimental measurements of anomalous couplings. Any experimental cut and apparatus efficiency may easily be introduced by rejecting some of the generated events.
The high precision of the program may vary depending on the input parameters. See details in the Long Write-up.
Mail program and other libraries published independently in Comput. Phys. Commun. must be loaded to run this library. There is no separate distribution of the code prepared for this version of the library. It is stored in its own sub-directory, archived with KORALZ, version 4.04 (Comput. Phys. Commun. 124(2000)233). The demonstration program for the library is also provided there.
