轻子普适性,|V_{us}|在τ衰变中寻找第二类电流

Lepton Universality, |V_{us}| and search for second class current in tau decays

Swagato Banerjee

摘要:

在SLAC国家加速器实验室的PEP-II e+e对撞机上,已经用BaBar探测器研究了数亿个τ衰变。荷电轻子普适性的最新结果和两个独立的|V_{us}|利用τ- -> e- nubar nu、mu- nubar nu、pi- nu、K- nu和KS 0 pi- nu衰变,在τ- -> pi- omega nu衰变中寻找第二类电流,其中还包含电荷共轭衰变模式。

英文摘要:

Several hundred million tau decays have been studied with the BaBar detector at the PEP-II e+e- collider at the SLAC National Accelerator Laboratory. Recent results on Charged Current Lepton Universality and two independent measurements of |V_{us}| using tau- -> e- nubar nu, mu- nubar nu, pi- nu, K- nu and KS0 pi- nu decays, and a search for Second Class Current in tau- -> pi- omega nu decays are presented, where the charge conjugate decay modes are also implied.
