准简并中微子情况下CP相位对有效中微子质量$m_{ee}$的影响

CP-phase effects on the effective neutrino mass $m_{ee}$ in the case of quasi-degenerate neutrinos

J. Maalampi, J. Riittinen

摘要:

我们研究了普通活动中微子的三个质量态实际上分裂成准简并态对的可能性,作为活动中微子与无菌中微子混合的结果,准简并态的$Δm^2_{kk'} \sim 10^{-12}$ eV $^2$或更小。虽然这些准简并对在实验室实验中看起来与单个活动态相同,但与活动-无菌混合相关的CP相位因子可能导致无中微子双β衰变实验中测量的有效电子中微子质量$m_{ee}$的抵消,从而揭示了态的分裂性质。

英文摘要:

We study the possibility that the three mass states of the ordinary active neutrinos actually split into pairs of quasi-degenerate states, with $Δm^2_{kk'} \sim 10^{-12}$ eV$^2$ or less, as a result of mixing of active neutrinos with sterile neutrinos. Although these quasi-degenerate pairs will look in laboratory experiment identical to single active states, the CP phase factors associated with active-sterile mixing might cause cancellations in the effective electron neutrino mass $m_{ee}$ measured in the neutrinoless double beta decay experiments thereby revealing the split nature of states.
