Measurement, parameterization and fast simulation of hadronic showers in lead

Measurements on longitudinal and lateral hadronic shower development in lead at 13 and 20 GeV are presented. It is shown that the longitudinal shower profile can be parametrized by a two component formula. A fast hadronic shower simulation method based on parametrization is described together with a possible method to introduce fluctuation in the shower development. A comparison between the simulation and data is also presented. (orig.)
