Some of the plots below were presented in the following talk:
Angle averages at B factories
by K. Miyabayashi at CKM 2012 (Cincinatti, USA).
This updates the results on α/φ_{2} angle prepared for Moriond 12,
including the measurements of Belle for the B→ρ⁰ρ⁰ and B→ππ decays shown at
CKM 2012. The Babar update of the B→ρπ analysis shown at the same conference is not included here.

Constraints on the angle α/ϕ_{2} from B→ππ
Constraint on α/ϕ_{2} from B→ππ
compared to the prediction from the global CKM fit (not including the αrelated measurements) α[fit]= (95.9^{+2.2}_{5.6})°.
The individual constraints are

α[Belle,ππ]∈[85.0°,148.0°]
 α[Babar,ππ]=(77.0^{+32.2}_{6.6})°
 α[WA,ππ]=(87.1^{+17.5}_{7.8})°
to be compared with the ones obtained at Moriond 2012

α[Belle,ππ]∈[68.0°,181.8°]
 α[Babar,ππ]=(77.0^{+32.2}_{6.6})°
 α[WA,ππ]=(92^{+12}_{11})°

Isospin triangles in B→ππ and B→ππ. One notices that the first triangle is almost flat, contrary to the second.


Prediction for the CP asymmetries in B→π^{+}π^{}
compared to the Babar and Belle measurements, and the World Average.


Constraints on the angle α/ϕ_{2} from B→ρρ
Constraints on α/ϕ_{2} from B→ρρ (BABAR, Belle and WA)
compared to the prediction from the global CKM fit (not including the αrelated measurements).
The indivdual constraints are

α[Belle,ρρ]=(84±13) °
 α[Babar,ρρ]=(92.4±6.4) °
 α[WA,ρρ]=(89.9^{+5.4}_{5.3})°
to be compared with the ones obtained at Moriond 2012

α[Belle,ρρ]=(84^{+14}_{15}) °
 α[Babar,ρρ]=(92.4±6.4) °
 α[WA,ρρ]=(89.9^{+5.4}_{5.5})°

Prediction for the branching ratio and longitudinal fraction of B→ρ^{0}ρ^{0}
compared to the Babar and Belle measurements.


Constraints on the angle α/ϕ_{2} from charmless B decays
Constraints on α/ϕ_{2} from the combination of B→ππ, ρπ, and ρρ for BABAR, Belle and WA,
compared to the prediction from the global CKM fit (not including the αrelated measurements).
The indivdual constraints are

α[Belle,all]∈ [168.7°,180.5°]
 α[Babar,all]=(92.8^{+5.8}_{6.9}) °
 α[WA,all]=(88.5^{+4.7}_{4.4})°
to be compared with the ones obtained at Moriond 2012

α[Belle,all]=(173.4^{+5.8}_{6.3}) °
 α[Babar,all]=(92.8^{+5.8}_{6.9})°
 α[WA,all]=(88.8^{+4.5}_{4.3})°
In the case of Belle, one notices that the standard peak emerges only at the 2 σ level.
