As measuring the spectra for the hadrons themselves is not always possible, it is often useful to study the decay products, or more precisely their spectra. Semileptonic decay channels are particularly useful for this purpose since detecting decay particles, such as electrons and positrons, is often relatively easy.\n\nIn this thesis, we have developed a simulation that allows us to study the decay of heavy-flavour hadrons. The simulation uses production cross sections obtained using the so-called SACOT-m_T scheme as a starting point. Furthermore, the simulation uses the PYTHIA event generator to model the decay processes. In this work, the production cross sections of the decay particles, in this case electrons and positrons, are the main object of interest. Our aim is to assess the validity of the use of the SACOT-m_T scheme by comparing our numerical results with experimental results and FONLL calculations. We find that our numerical results are in good correspondence with experimental data and therefore we can consider our simulation to be successful. Thus, we can also conclude that the use of the SACOT-m_T scheme is justified in this context.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2023-05-22T11:04:34Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-05-22T11:04:34Z (GMT).
