论文摘要
我们研究了未来中微子中微子振荡（MBRO）实验在研究中微子波包撞击中的潜力。在我们的研究中，我们将中微子视为波数据包，并使用相应的中微子风味过渡概率。波数据包的离域，分离和扩散会导致反谐和分散效应，从而通过取决于初始中微子波数据包中能量不确定性的量来改变平面波中微子的振荡模式。我们发现，由于基线足够长，MBRO实验可能对波包的影响很敏感，并且由于出色的检测器能量分辨率而观察到对中微子振荡的小校正的能力。除了研究对逆转参数的约束外，我们还研究了对未来中等基线反应器中微子振荡实验中测量$θ_{12} $和其他振荡参数精确度的潜在波包影响。此外，我们还探索了研究这种异国中微子物理学的额外检测器的潜在优势。
We examine the potential of the future medium-baseline reactor neutrino oscillation (MBRO) experiments in studying neutrino wave-packet impact. In our study, we treat neutrinos as wave packets and use the corresponding neutrino flavor transition probabilities. The delocalization, separation and spreading of the wave packets lead to decoherence and dispersion effects, which modify the plane-wave neutrino oscillation pattern, by amounts that depend on the energy uncertainties in the initial neutrino wave packets. We find that MBRO experiments could be sensitive to the wave-packet impact, since the baseline is long enough and also the capability of observing small corrections to the neutrino oscillations due to excellent detector energy resolution. Besides studying the constraints on the decoherence parameter, we also examine the potential wave-packet impacts on the precision of measuring $θ_{12}$ and other oscillation parameters in the future medium-baseline reactor neutrino oscillation experiments. Moreover, we also probe the potential benefits of an additional detector for studying such exotic neutrino physics.
