CKM $\gamma$ phase from $B\to K\pi \pi$

Ignacio Bediaga, Gabriel Guerrer, Jussara M. de Miranda

We discuss a method to extract the CKM $\gamma$ angle combining Dalitz plot analysis of $B^{\pm }\to K^{\pm }{\pi }^{+}{\pi }^{-}$ and untagged $B^0$, ${\bar{B}}^0\to K_s{\pi }^{+}{\pi }^{-}$. The method also all…
