摘要:

本文介绍了NA 48、NA 48/1和NA 48/2实验的最新结果,包括:K~+-> 3 π衰变的直接CP破坏和Dalitz图斜率测量,K~+-> π~+-π 0 π 0和K_e~4衰变的π π散射效应,以及K_e~4的形状因子和分支分数;辐射带电K介子和超子衰变的测量,中性和带电K介子的半轻子衰变; KL--> pi + pi-分支比和|eta +-|用Kl2衰变检验轻子的普适性。

英文摘要:

Recent results from the experiments NA48, NA48/1 and NA48/2 are presented, including: direct CP-violation and Dalitz plot slopes measurements for K+- --> 3 pi decays; pi pi scattering effects in K+- --> pi+- pi0 pi0 and Ke4 decays, as well as Ke4 form factors and branching fraction; measurements on radiative charged kaons and hyperon decays, semileptonic decays of neutral and charged kaons; KL --> pi+ pi- branching ratio and |eta+-| measurement; lepton universality check with Kl2 decays.
