Physics Letters B, 2003•ElsevierThe production fractions of charged and neutral b-hadrons in b-quark events from Z0 decays
have been measured with the DELPHI detector at LEP. An algorithm has been developed,
based on a neural network, to estimate the charge of the weakly-decaying b-hadron by
distinguishing its decay products from particles produced at the primary vertex. From the
data taken in the years 1994 and 1995, the fraction of b ̄-quarks fragmenting into positively
charged weakly-decaying b-hadrons has been measured to be:[Formula: see text] …
