基于唯象学模型的洛伦兹破缺限制研究
Study of Lorentz violation limit based on phenomenological model
摘要
Abstract
Lorentz invariance is one of the fundamental symmetries in physics.However,some theories of quantum gravity proposed that Lorentz symmetry might be broken at high energy stages,resulting in lorentz violation,which allows photons to propagate with a speed related to their own energy rather than a constant speed of light.Currently this violation theory is based on an image-only model utilizing time delays or spectral delays of photons in y-rays by high-energy detectors to place limits on the lorentz violation energy scale.Based on the image-only model,by comparing the limiting results of the two de-lays in gamma bursts,we find that the limiting results of the spectral delay are generally smaller than those of the temporal delay by 3～4 orders of magnitude.In order to make the results more confident,we also calculate the time-delay limiting re-sults for GRB 190114C in the 1～14 s time period.Compared with the spectral delay results for the same time period,the delays are still 3 orders of magnitude different,which may be generated due to the properties of the spectral delays.关键词
