Classification of the hadronic decays of the Z 0 into b and c quark pairs using a neural network
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 Z 0, collected by DELPHI during 1991, into three classes according to the flavour of the original quark pair: u u+d d+s s (unresolved), c c and b b . The classif...
