中微子II可能的量子引力效应探索:中微子传播中的洛伦兹破坏

Exploration of Possible Quantum Gravity Effects with Neutrinos II: Lorentz Violation in Neutrino Propagation

Alexander Sakharov, John Ellis, Nicholas Harries, Anselmo Meregaglia, Andre Rubbia

摘要:

有人认为,高能粒子与时空泡沫结构的相互作用被认为是由量子引力(QG)效应产生的,可能会违反洛伦兹不变性,因此它们不会以光速传播。利用超新星爆炸和OPERA长基线中微子实验的数据,我们考虑了高能中微子传播中线性或二次破坏洛伦兹不变性的极限,v/c=[1 +-(E/M_ \nuQG 1)]或[1 +-(E/M_v QG 2}^2]。

英文摘要:

It has been suggested that the interactions of energetic particles with the foamy structure of space-time thought to be generated by quantum-gravitational (QG) effects might violate Lorentz invariance, so that they do not propagate at a universal speed of light. We consider the limits that may be set on a linear or quadratic violation of Lorentz invariance in the propagation of energetic neutrinos, v/c=[1 +- (E/M_\nuQG1)] or [1 +- (E/M_νQG2}^2], using data from supernova explosions and the OPERA long-baseline neutrino experiment.
