摘要：Several hadronic event shape observables at LEP and SLC are sensitive to
the b-quark mass through the reduced gluon radiation which occurs compared to lighter
flavours. Detailed measurements by ALEPH, DELPHI, OPAL and SLD collaborations
at
p
s = MZ have established the e
ect and have enabled determinations of the b-quark
mass at this energy scale. The most recent results are presented and discussed.
