在LHC b的树主导衰变中CKM角γ的测量

Measurements of the CKM angle gamma in tree-dominated decays at LHCb

Stefania Ricciardi

摘要:

我们审查的第一次测量CKM角γ从LHCb。这些测量是在b -> u和b -> c树级振幅主导的b-强子衰变中进行的,由此可以确定伽马而没有理论上的不确定性。通过对B- -> Dh-(h= K,pi)衰变的结果进行平均来实现精度,其中D -> h+h-,D -> K+pi-,D -> K+pi-pi+pi-,D -> K_S^0h+h-。展望这些和未来的测量伽马使用中性b-强子衰变进行了简要讨论。

英文摘要:

We review the first measurements of the CKM angle gamma from LHCb. These measurements have been performed with b-hadron decays dominated by b -> u and b -> c tree-level amplitudes, from which gamma can be determined without theoretical uncertainties. Precision is achieved by averaging results from B- -> Dh- (h= K,pi) decays with D -> h+h-, D -> K+pi-, and D -> K+pi-pi+pi-, and D -> K_S^0h+h-. Prospects for these and future measurements of gamma using neutral b-hadron decays are briefly discussed.
