洛伦兹破坏理论中π介子的类切伦科夫辐射

Cerenkov-Like Emission of Pions by Photons in a Lorentz-Violating Theory

Brett Altschul

摘要:

在洛伦兹破坏的存在下,切伦科夫类过程$γ\rightarrowγ+π^{0}$可能变得允许足够高能量的光子。超过阈值的光子将通过π介子发射迅速失去能量。能量高达80 TeV的传播光子在地球上被观测到,这一事实使我们能够在$7\times 10^{-13}$水平上对各向同性洛伦兹破坏参数进行单侧约束;这比以前的最佳结果好了一个数量级以上。

英文摘要:

In the presence of Lorentz violation, the Cerenkov-like process $γ\rightarrowγ+π^{0}$ may become allowed for sufficiently energetic photons. Photons above the threshold would lose energy rapidly through pion emission. The fact that propagating photons with energies of up to 80 TeV survive to be observed on Earth allows us to place a one-sided constraint on an isotropic Lorentz violating parameter at the $7\times 10^{-13}$ level; this is more than an order of magnitude better than best previous result.
