====== TTP00-28 $b$ Quark Physics with $2 \times 10^9$ $Z$ Bosons ====== 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. |**A.
