A classifier based on a feed-forward neural network has been used for separating a sample of about 123 500 selected hadronic decays of the Z0, collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: View the MathML source (unresolved), View the MathML source and View the MathML source. The classification has been used to compute the partial widths of the Z0 into b and c quark pairs. This gave View the MathML source, View the MathML source.
