Measurement of time-dependent CP asymmetries in B0 → D(*)±π± decays and constraints on sin(2β + γ)
The CP-violating asymmetries in fully reconstructed B0 → D(*)∓π∓ decays and constraints on sin(2β + γ) were investigated. The time evolution of decays was sensitive to γ because of interference between the Cabibbo-Kobayashi-Maskawa (CKM) favored decay and doubly CKM-suppressed decay. The consistency...

| description | The CP-violating asymmetries in fully reconstructed B0 → D(*)∓π∓ decays and constraints on sin(2β + γ) were investigated. The time evolution of decays was sensitive to γ because of interference between the Cabibbo-Kobayashi-Maskawa (CKM) favored decay and doubly CKM-suppressed decay. The consistency of data was computed with given value of sin(2β + γ) by counting fraction of simulated experiments for which χ 2(sin(2β + γ))-χmin2 was smaller. The lower limit on |sin(2β + γ)| was observed at 68% confidence level which drops from 0.69 to 0.60. |
