Abstract
The selection efficiencies and approximate background for the Bd0 → D*±:a1∓ (1260) mode are determined from studies based on Monte Carlo generated samples. It was found that evaluated annual rate of such decay events makes a hope for a better than at present precision of the CKM unitary triangle angle measurement. Estimated uncertainties depending on value of the γ angle are 10.0±1.1 for γ 40°, 7.8±0.3 for γ = 60° and finally 7.0 ± 0.2 for γ = 80°. [ABSTRACT FROM AUTHOR]
