Fully probing the Cabibbo-Kobayashi-Maskawa unitarity triangle at the Υ(4S) resonance

We analyze the joint decays of C=±{}1 Bd⁰B{} d⁰ pairs at a symmetric B factory. A few time-integrated measurements of decay rates and CP-violating asymmetries are proposed for Bd⁰,B{} d⁰π⁺{{{π}}}^{{{-}}}$,${{{π}}}⁰π⁰,{ψ}KS and Bᵤ^±{→}π^±{{{π}}}⁰$ both on the {Υ}(4S) resonance and just above it. We show that it is possible to extract three angles of the Cabibbo-Kobayashi-Maskawa unitarity triangle from such measurements unambiguously, even in the presence of significant final-state strong interactions and in the absence of exclusive Bₛ⁰ versus B{} ₛ⁰ decay modes.
