It has been suggested to realize a factory for 10^9 Z^0 through a
linear e^+e^- collider with polarized beams. Very likely the relevant CP
studies for B mesons will already have been performed at the B
factories by that time, hence GIGA-Z will be a third generation b
physics experiment. Yet such a facility would provide us with unique
opportunities in the domain of beauty physics that would be of
essential significance even in 2010: (1) Production and decay of
polarized beauty baryons; (2) searching for and probing transitions
driven by b –> q \nu \bar{\nu}; (3) detailed and comprehensive
studies of inclusive semileptonic B_s decays.
