K^0与\bar{K}^0到π^+π^-π^0衰变中CPT对称性的检验

A Test of CPT Symmetry in K^0 vs \bar{K}^0 to π^+π^-π^0 Decays

Zhi-zhong Xing

摘要:

我证明了,如果K^0-\bar{K}^0混合中存在CPT违反,则K^0 vs \bar{K}^0 \to π ^+π^-π^0衰变中的CP违反不对称性与K_L \to π^+π^-、K_L \to π^0π^0或半轻子K_L跃迁中的CP违反不对称性不同。在一个超级香料工厂(例如,将为我们提供一个中性K介子系统CPT对称性的强有力的检验。

英文摘要:

I show that the CP-violating asymmetry in K^0 vs \bar{K}^0 \to π^+π^-π^0 decays differs from that in K_L \to π^+π^-, K_L \to π^0π^0 or the semileptonic K_L transitions, if there exists CPT violation in K^0-\bar{K}^0 mixing. A delicate measurement of this difference at a super flavor factory (e.g., the ϕfactory) will provide us with a robust test of CPT symmetry in the neutral kaon system.
