论文摘要
在本文中,我们研究了未来加速器(T2HK),未来大气(ICAL)和未来反应堆(JUNO)中微子实验的协同作用,以确定中微子质量有序。 T2HK只能针对$δ_ {\ rm cp} $的有利值测量质量排序,而Juno的质量排序敏感性取决于能量分辨率。我们的结果表明,通过T2HK,ICAL和JUNO的组合,即使是$δ_ {\ rm CP} = 0^\ Circ $的不利值,T2HK的不利于价值的敏感性也可以达到7.2 $σ$,对于t2hk和Circ $ circ $ circ $ circ $ circ $ circ $ circ $ circ $ circ $ circ $ cirt and circ $ cirt and cirt cirp $ cirt and cirt cirt of Juno能量的最保守价值和5 $ \%/\ \ sqrt sqrts的juno能源的价值最保守。协同作用之所以出现,是因为不同的振荡通道更喜欢$ |Δm_{31}^2 | $的不同值,当时质量订购$χ^2 $最小化时。在这种情况下,我们还研究了:(i)朱诺的能量分辨率变化的影响,(ii)$θ_{23} $的不同真实值的较长运行时间的影响,以及(iv)八度二聚体在确定中性质量序列中的影响。
In this paper we study the synergy among the future accelerator (T2HK), future atmospheric (ICAL) and future reactor (JUNO) neutrino experiments to determine the neutrino mass ordering. T2HK can measure the mass ordering only for favorable values of $δ_{\rm CP}$, whereas the mass ordering sensitivity of JUNO is dependent on the energy resolution. Our results show that with a combination of T2HK, ICAL and JUNO one can have a mass ordering sensitivity of 7.2 $σ$ even for the unfavorable value of $δ_{\rm CP} = 0^\circ$ for T2HK and most conservative value of JUNO energy resolution of 5$\%/\sqrt{E(MeV)}$. The synergy mainly comes because different oscillation channels prefer different values of $|Δm_{31}^2|$ in the fit when the mass-ordering $χ^2$ is minimized. In this context we also study: (i) effect of varying energy resolution of JUNO, (ii) the effect of longer run-time of ICAL, (iii) effect of different true values of $θ_{23}$ and (iv) effect of octant degeneracy in the determination of neutrino mass ordering.
