Abstract

A new method to extract the weak phase γ is suggested by exploiting

\vec{B} {DK}^{(*)}

decay modes that are not Cabibbo suppressed, using the isospin relations, and ignoring the annihilation diagram as usual. Assuming a

3 \times 10^{8} B \bar{B}

pair at B factories, one can determine γ with a 3σ accuracy for

80 ° ≲ γ ≲ 150 °

using

\vec{B} DK

modes and for

50 ° ≲ γ ≲ 170 °

using

\vec{B} {DK}^{*}

modes.
