英文摘要: The influence of strong and electroweak penguin amplitudes in B/(B) over bar --> pi(+)pi(-) is investigated in connection with the determination of the unitarity triangle angle a of the CKM matrix. A relation between the observable asymmetry, the angle alpha, and the penguin amplitude is established. A model calculation of the penguin amplitude shows that the CP asymmetry in B-0 --> pi(+)pi(-) decays is only mildly influenced by the penguin amplitudes. Experimental limits on pure penguin and penguin dominated processes are consistent with the model. This information also suggests in a rather model-independent way that penguin amplitudes will not be a serious complicating factor in the determination of a from the pi(+)pi(-) time-dependent asymmetry.
