非么正效应在中微子振荡测量中能突出吗?

Can Non-unitary Effect be Prominent in Neutrino Oscillation Measurements?

Lei Lü, Wenyu Wang, Zhaohua Xiong

摘要:

在中微子实验的条件下,普通中微子的混合矩阵仍然可以有小的么正性破坏。我们引入了一个准酉矩阵来解释这种破坏,并提出了一个自然的方案来参数化它,定义了一个准酉因子$Δ_{\rm QF}$,并在中微子振荡实验中进行了测量,数值计算结果表明,提高实验精度可能有助于揭示中微子混合的秘密.

英文摘要:

Subject to the neutrino experiments, the mixing matrix of ordinary neutrinos can still have small violation from unitarity. We introduce a quasi-unitary matrix to interpret this violation and propose a natural scheme to parameterize it. A quasi-unitary factor $Δ_{\rm QF}$ is defined to be measured in neutrino oscillation experiments and our numerical results show that improvement of experimental precision may help us figure out the secret of neutrino mixing.
