Phys. Rev. D 61, 112001 (2000) [14 pages]Impact of D0-D0̅ mixing on the experimental determination of γReceived 10 December 1999; published 1 May 2000 Several methods have been devised to measure the weak phase γ using decays of the type B±→DK±, where it is assumed that there is no mixing in the D0-D0¯ system. However, when using these methods to uncover new physics, one must entertain the real possibility that the measurements are affected by new physics effects in the D0-D0¯ system. We show that even values of xD and/or yD around 10-2 can have a significant impact in the measurement of sin2γ. We discuss the errors incurred in neglecting this effect, how the effect can be checked, and how to include it in the analysis. © 2000 The American Physical Society URL:
