Simulation input

The simulation input is a list of events, each of which contains a list of particles and their momenta. This list may be generated by Monte Carlo event generators, which produce distributions of particle species and momenta that approximate the physical distributions (Venus, UrQMD, Fritiof), or by "hand" according to any other distribution. For embedding studies, the event of MC particles is usually generated by "hand" with a fixed number of particles per event of a single species and with a parametrized momentum distributions ("Micky Mouse" simulation). These distributions can either be a parametrization of realistic particle distributions or can also be flat in phasespace. The latter option has the advantage that correction factors calculated from the embedding procedure have comparable statistical significance for all y-pt bins. In order to take the real phasespace population into accoun, the input particles should be given weights according to the realistic distributions when calculating the final correction factors.

Here you can see as an example a simple "Micky Mouse" simulation of K* production and here a description of the model "Venus"
