Inclusive studies of pion-nucleus interactions in the framework of the Lund fragmentation model

The Lund fragmentation model implemented through Monte Carlo FRITIOF is used to analyse the data from pion-emulsion interactions in a strong pulsed magnetic field at PLab=50 GeV/c. The model is based on the concept of classical strings and uses the longitudinal excitation as a means of string formation. The subsequent string fragmentation follows the Lund fragmentation scheme. Detailed inclusive studies based on rapidity, momenta, transverse momenta, etc of the fast pions produced in such interactions are undertaken. The analysis is motivated by the fact that such inclusive studies have not been performed earlier and to make detailed tests of the model to establish correctness of the procedures relating to the dynamics involved in the particle production. This also gives interesting comparison between the data and the model predictions. (author)
