Gamma Combination from the UTfit goup

We use the relevant post-Moriond 2012 HFAG averages as inputs.

The results of combination:

The angle \gamma of the CKM triangle can be measured comparing V_{cb} and V_{ub} mediated transitions in B \rightarrow D^{(*)}K^{(*)} decays. The decays proceed through the following diagrams:

These diagrams are practically free from the New Physics contribution.

There are three methods to extract relevant information, each of them deals with its own D^{0} decay:

  • a singly Cabibbo-suppressed} CP eigenstate, like D^{0}\rightarrow h^+h^- (h=\pi,K) for Gronau-London-Wyler (GLW)
method;
  • a doubly Cabibbo-suppressed flavor eigenstate, like D^{0}\rightarrow K^+\pi^- for Atwood-Dunietz-Soni (ADS) method;
  • a Cabibbo-allowed self-conjugate 3-body state, like \D^0 \rightarrow \KS\pip\pim for Giri-Grossman-Soffer-Zupan (GGSZ) method.
