Measurement of the angle α at BABAR
نویسنده
چکیده
We present recent measurements of the CKM angle α using data collected by the BABAR detector at the PEP-II asymmetric-energy ee collider at the SLAC National Accelerator Laboratory, operating at the Υ (4S) resonance. We present constraints on α from B → ππ, B → ρρ and B → ρπ decays.

Measurements of charmless B decays related to α at BABAR Vincenzo LOMBARDO
We report recent measurements of the CKM angle α using data collected by the BABAR detector at the PEP-II asymmetric-energy e + e − collider at the SLAC National Accelerator Laboratory. In addition to improved constraints on α from the decays B ± → ρ ± ρ 0 , we also present preliminary results of neutral and charged B meson decays to K 1 (1270)π and K 1 (1400)π and its impact on the estimate fo...

متن کاملMeasurements of γ/φ3 at B factories
One angle, φ1 (or β) , has been measured with high precision at BaBar [1] and Belle [2] experiments. The measurement of the angle φ2/α is more difficult due to theoretical uncertainties in calculation of the penguin diagram contribution. Precise determination of the third angle, φ3/γ, is possible, e.g. , in the decays B → DK. Although it requires a lot more data than for the other angles, it is...
متن کاملMeasurement of the CKM Angles at BaBar and Belle
The primary goal of the BaBar and Belle experiments is to overconstrain the CKM Unitarity Triangle. Measurements of the angles of this triangle, known as β, α, and γ (or φ1, φ2, and φ3) give insight into the Standard Model description of CP violation in the quark sector. BaBar and Belle have recorded almost 1 ab−1 combined, and have measured β to high precision. Measurements of α and γ are less...
