论文摘要
我们表明，来自字符串/D-Brane理论的时空泡沫模型预测了一种场景，其中中微子可以具有线性依赖能量的速度变化，以及中微子和抗肿瘤之间的不对称性，表明洛伦兹和cpt对称违反中子的可能性。这种情况得到了从Icecube Ultrahigh-Energy Neutrino事件与伽马射线爆发的可能关联的现象学猜想的支持。它也与超纤毛中微子速度上的能量衰减通道设定的约束〜（我们认为，在衰减过程中对能量弹药保护的合理侵犯可能是这些中微子稳定传播的原因，因此逃避相关约束。
We show that the space-time foam model from string/D-brane theory predicts a scenario in which neutrinos can possess linearly energy dependent speed variation, together with an asymmetry between neutrinos and antineutrinos, indicating the possibility of Lorentz and CPT symmetry violation for neutrinos. Such scenario is supported by a phenomenological conjecture from the possible associations of IceCube ultrahigh-energy neutrino events with the gamma-ray bursts. It is also consistent with the constraints set by the energy-losing decay channels~(e.g., $e^{+}e^{-}$ pair emission, or neutrino splitting) upon superluminal neutrino velocities. We argue that the plausible violations of energy-momentum conservation during decay may be responsible for the stable propagation of these neutrinos, and hence for the evasion of relevant constraints.
