论文摘要
电荷 - 准时（CPT）对称性决定了中微子和抗中性旋转的振荡参数是相同的。这些颗粒的不同质量和混合参数可能会给我们带来中微子扇形中CPT违规的可能提示。使用这种方法，我们讨论了长基线和大气中微子实验确定质量平方分裂之间差异的能力（$Δm^{2} _ {32} _ {32}-Δ\ bar {m} （$ \ sin^{2}θ_{23} - \ sin^{2} \barθ_{23} $）的中微子和抗内膜。我们显示了T2K，NOVA和INO实验对此类CPT的关节敏感性，该CPT违反了中微子和抗神经内脏的不同可能组合中可观察到的物体。
Charge-Parity-Time (CPT) symmetry governs that the oscillation parameters for neutrinos and anti-neutrinos are to be identical. Different mass and mixing parameters for these particles may give us a possible hint for CPT violation in the neutrino sector. Using this approach, we discuss the ability of long-baseline and atmospheric neutrino experiments to determine the difference between mass squared splittings ($Δm^{2}_{32}-Δ\bar{m}^{2}_{32}$) and atmospheric mixing angles ($\sin^{2}θ_{23}-\sin^{2}\barθ_{23}$) of neutrinos and anti-neutrinos. We show the joint sensitivity of the T2K, NOvA and INO experiments to such CPT violating observables in different possible combinations of octant for neutrinos and anti-neutrinos.
