论文摘要
我们显示了通过在沙丘实验中测量Majorana CP阶段发现中微子性质的可能性。该阶段是由一个变质环境打开的，该阶段可能是由Planck量表以物理学来源的。与T2HK测量值相比，在DIRAC CP违规阶段的测量中，$δ_{\ Mathrm {cp}} $的大量失真观察到，由于eNullecormentions和t2hk的测量值而言，由于反应性和非零虫阶段而言。在沙丘上执行Majorana阶段的测量时，它的精度为23（21）$ \％$，对于折叠参数$γ= 4.5（5.5）\ times 10^{ - 24} \ mathrm {gev} $，大群相位等于$ 1.5π$。后者的精度类似于以当前DIRAC CP违规阶段测量在T2K实验上获得的精度。
We show the possibility to discover the neutrino nature by measuring the Majorana CP phase at the DUNE experiment. This phase is turned on by a decoherence environment, possibly originated by physics at the Planck scale. A sizable distortion in the measurement of the Dirac CP violation phase $δ_{\mathrm{CP}}$ is observed at DUNE when compared with T2HK measurement due to decoherence and non-null Majorana phase. Being that, when the measurement of the Majorana phase is performed at DUNE, it reaches a precision of 23 (21) $\%$ for a decoherence parameter $Γ=4.5(5.5)\times 10^{-24} \mathrm{GeV}$ and a Majorana phase equal to $1.5 π$. The latter precision is similar to the one obtained at the T2K experiment at its current Dirac CP violation phase measurement.
