Query: Measurement of the CKM angle alpha with the B-factories   B-meson decays involving b->u transitions are sensitive to the Unitarity
Triangle angle alpha (or phi_2). The B-factories at SLAC and KEK have made
significant progress toward the measurement of alpha in recent years. This
paper summarizes the results of the B-factories' constraints on alpha.
