Description
We present the updated analysis of Bd, Bs , and Lambda_b decays into
charmless two-body
final states using 6/fb of data collected by the CDF experiment.
We report the first evidence for
the pure-annihilation decay Bs->pi^+pi^- and improved limits
on the Bd->K+K- branching ratio.
We also report the first measurement of branching fractions
and CP-violating asymmetries
of doubly-Cabibbo suppressed B+ --> D0 K decays in hadron collisions,
using the approach
proposed by Atwood, Dunietz, and Soni (ADS) to infer information
on the CKM angle gamma in
7.0 fb-1 of data. The relevant parameters are determined with accuracy
competitive with best B factory measurements.
