长基线中微子振荡实验中反中微子运行的一种新方法

A new approach to anti-neutrino running in long baseline neutrino oscillation experiments

摘要:

我们研究了用静止μ子衰变产生的反中微子取代长基线中微子振荡实验中反中微子运行的可能性。这些中微子的低能量允许在掺钆水切伦科夫探测器中使用逆β衰变进行探测。我们表明,这种方法产生的反中微子事件样本的五倍大的因素。在θ_13处发现了质量分级和轻子CP破坏,并与中微子和反中微子联合运行的常规超束实验进行了比较。我们发现,这种方法产生了一个大大提高了达到CP破坏和theta_13,而留下的能力来衡量的质量等级完好无损。

英文摘要:

We study the possibility to replace the anti-neutrino run of a long baseline neutrino oscillation experiment, with anti-neutrinos from muon decay at rest. The low energy of these neutrinos allows the use of inverse beta decay for detection in a Gadolinium-doped water Cerenkov detector. We show that this approach yields a factor of five times larger anti-neutrino event sample. The resulting discovery reaches in theta_13, the mass hierarchy and leptonic CP violation are compared with those from a conventional superbeam experiment with combined neutrino and anti-neutrino running. We find that this approach yields a greatly improved reach for CP violation and theta_13 while leaving the ability to measure the mass hierarchy intact.
