【 摘 要 】

We explore the possiblity of extracting the weak phase $𝛾$ from pure tree decays $𝛬_{b}→ 𝛬 (D^{0},overline{D}^{0},D^{0}_{ext{CP}})$ in a model independent way. We find the CP violating phase $𝛾$ can be determined cleanly without any hadronic uncertainties. Furthermore, these decays are free from the penguin pollution and neither tagging nor time dependent studies are required for the extraction.
