INTEGRAL伽马射线暴中洛伦兹破坏的研究

Study of Lorentz violation in INTEGRAL Gamma-Ray Bursts

Raphael Lamon, Nicolas Produit, Frank Steiner

摘要:

我们利用INTEGRAL探测到的伽马射线暴,寻找可能由量子引力效应引起的时间滞后。这颗卫星的优点是,我们可以掌握每个探测到的单光子的能量和到达时间,这提高了时间分辨率的精度。我们提出了一种新的方法,寻求时间滞后的未分组数据使用极大似然法和支持我们的结论与蒙特卡罗模拟。对数据的分析得出了一个远低于普朗克质量的质量标度,但是如果有更好的伽马射线暴统计数据,普朗克质量的值可能会增加。此外,我们不同意以前的研究中,一个非单调函数的红移是用来执行线性拟合。

英文摘要:

We search for possible time lags caused by quantum gravitational (QG) effects using gamma-ray bursts (GRBs) detected by INTEGRAL. The advantage of this satellite is that we have at our disposal the energy and arrival time of every detected single photon, which enhances the precision of the time resolution. We present a new method for seeking time lags in unbinned data using a maximum likelihood method and support our conclusions with Monte Carlo simulations. The analysis of the data yields a mass scale well below the Planck mass whose value may however increase if better statistics of GRBs were available. Furthermore, we disagree with previous studies in which a non-monotonic function of the redshift was used to perform a linear fit.
