Title : Tagging with fully reconstructed B's in B-factory experiments
Authors : Takahiro Matsumoto
Abstract : 
In B-factory experiments, large numbers of BBbar meson pairs are
produced from the Upsilon(4S) resonance. By fully reconstructing one B
decay, we can obtain single B meson beams with known
momentum and flavor. This unique method has great advantages for
studying decays that include neutrinos and taus (such as B->Xu l nu,
tau  nu, K nu nubar and D tau nu etc.), which are sensitive
probes for new physics. We shall report on an algorithm for fully
resonstructing various hadronic and semileptonic B decays at Belle,
and discuss how to improve its efficiency for future studies.
