Abstract
The BaBar experiment has collected a large sample of B meson decays
during its running time, which has facilitated the search for rare and
very rare decays. The rare decay B→τν
is a purely leptonic decay of
the B meson, and represents an opportunity to study properties of the B
meson unmeasurable in other decay modes, and also an exciting opportunity
to constrain New Physics effects beyond the standard model. Current
results from BaBar and Belle have provided evidence for this decay - the
next round of analyses hope to increase the sensitivity of the experiment
by utilising multivariate analysis techniques. Current measurements, and
prospects for analysis with the full BaBar dataset will be described.
