利用希格斯玻色子与光子的有效相互作用，研究了观测洛伦兹不变性微小偏离的前景。一个质量维度为五的单一算符足以描述双光子衰变通道中洛伦兹违反的所有主要特征。将理论修正衰变率与大型强子对撞机上ATLAS和CMS合作组测量的观测信号强度进行比较，表明对洛伦兹违反相应系数的估计可达到的灵敏度约为\(10^{-4}\)GeV\(^{-1}\)。
英文摘要
The prospects for observing small departures from Lorentz invariance are studied using effective interactions of the Higgs boson with photons. A single operator of mass-dimension five suffices to describe all leading signatures of Lorentz violation in the diphoton decay channel. Comparison of the theoretical modified decay rates with observed signal strengths measured by the ATLAS and CMS Collaborations at the Large Hadron Collider indicates an estimated attainable sensitivity to the corresponding coefficients for Lorentz violation of order $10^{-4}$ GeV$^{-1}$.
