论文摘要
最近,一系列对宇宙光子和中微子飞行时间的分析表明,光的速度\ emph {in Vacuo}采用了能量依赖性的表格$ v(e)\ simeq 1-e/e/e _ {\ text {liv}}}}}}^{γ} $ _} 3.6 \ times 10^{17}〜\ text {gev} $,与此同时,建议中微子的速度为$ v(e)\ simeq 1 \ pm e/e/e/e/e _ {\ text {liv}}}} 10^{17}〜\ text {gev} $和$ \ pm {} $表示螺旋依赖性。这张小说的图片立即敦促我们提供令人满意的理论解释。在预测量子重力速度变化的所有尝试中,我们发现循环量子重力可以作为始终如一地解释上述图片的良好候选者。
Recently a series of analyses on the flight time of cosmic photons and neutrinos suggests that the speed of light \emph{in vacuo} takes the energy-dependent form $v(E)\simeq 1-E/E_{\text{LIV}}^{γ}$ with $E_{\text{LIV}}^{γ}\approx 3.6\times 10^{17}~\text{GeV}$, and meanwhile the speed of neutrinos is proposed to be $v(E)\simeq 1\pm E/E_{\text{LIV}}^{ν}$ with $E_{\text{LIV}}^{ν}\approx 6.5\times 10^{17}~\text{GeV}$ and $\pm {}$ representing the helicity dependence. This novel picture immediately urges us to provide a satisfactory theoretical explanation. Among all the attempts to predict the speed variations from quantum gravity, we find that loop quantum gravity can serve as a good candidate for explaining the aforementioned picture consistently.
