# Library of SM and anomalous WWγ couplings for the e+e−→f f ̄ nγ Monte Carlo programs

## Description

Abstract A brief description of the library of the Standard Model and anomalous WWγ coupling contribution to the matrix element for e^+ e^-→ vv̄nγ process is given. It can be used with any Monte Carlo program for e^+ e^-→ f f̄nγ processes. A working example of the application for the KORALZ version 4.04 is also provided. Title of program: GengLib, version 2.0 Catalogue Id: ADKY_v1_0 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 ...
