用大气中微子探测$ν_3$存在不可见衰变时轻子$δ_{CP}$的灵敏度

Probing the sensitivity to leptonic $δ_{CP}$ in presence of invisible decay of $ν_3$ using atmospheric neutrinos

摘要:

中微子振荡的主要参数之一是轻子$δ_{CP}$相,其值还没有非常精确地确定。由于中微子的质量很小,但质量有限,因此它们可以进行可见和不可见的衰变。本文利用大气中微子和反中微子事件分析了第三质量本征态$ν_3$的不可见衰变对$δ_{CP}$灵敏度的影响。检测器的分辨率和系统的不确定性的影响进行了研究,以确定最佳的分辨率和效率所需的检测器,以获得显着的灵敏度,即使在存在的衰变。

英文摘要:

One of the main neutrino oscillation parameters whose value has not been determined very precisely is the leptonic $δ_{CP}$ phase. Since neutrinos have a tiny but finite mass they can undergo decay both visibly and invisibly. The effect of invisible decay of the third mass eigen state $ν_3$ on the sensitivity to $δ_{CP}$ is analysed here using atmospheric neutrino and anti-neutrino events. Effects of detector resolutions and systematic uncertainties are studied to identify the optimum resolutions and efficiencies required by a detector to obtain a significant sensitivity even in presence of decay.
