CLEO-c在γ测量中的关键作用

The crucial role of CLEO-c in the measurement of gamma

Christopher Thomas

摘要:

测量CKM角γ的最灵敏的方法是利用B(+/-)->DK(+/-)衰变中的干涉,其中D介子衰变到强子终态。CLEO-c处psi(3770)的量子相关衰变分析提供了关于Dalitz平面上D 0和D 0 bar之间强相位差的宝贵信息。将给出D-> K 0 PiPi和D-> K 0 KK衰变的分析结果。

英文摘要:

The most sensitive method to measure the CKM angle gamma is to exploit interference in B(+/-)->DK(+/-) decays, with the D-meson decaying to a hadronic final state. The analysis of quantum-correlated decays of the psi(3770) at CLEO-c provides invaluable information on the strong-phase difference between the D0 and D0bar across the Dalitz plane. Results from analyses of the decays D->K0PiPi and D->K0KK will be presented.
