Hi,

here is the abstract for the Vub analysis on the recoil of fully 
reconstructed B mesons. We aim to be ready also with the unfolding 
on that time scale but it is not guaranteed that we will be ready 
with a paper draft for the unfolding on the same time scale as the 
Vub result.
Therefore, we have been vague and we are only talking about studying 
distributions of kinematical variables and using spectral moments 
from semileptonic B decays which would allow us to show also the
result for the unfolding.

Cheers,
Heiko on behalf of the VubRecoil team


ABSTRACT
--------
Charmless semileptonic decays, B -> X_u l nu, are studied in a sample of 
232 million B Bbar decays recorded with the BaBar detector, in events 
where the decay of the second B meson is fully reconstructed.
Distributions of various kinematic variables characterising B -> X_u l nu 
decays are studied. Partial branching fractions DeltaB(B -> X_u l nu) are 
measured in kinematic regions where the dominant background from 
semileptonic B decays to charm is reduced.
The CKM matrix element |V_{ub}| is extracted by using theoretical 
calculations of phase space acceptances. Theoretical uncertainties in this 
extrapolation are reduced by using the inclusive b -> s gamma photon
and spectral moments from semileptonic B decays.
