Probing Lorentz invariance via diphoton decays of the Higgs boson
Alan Kostelecky, Connor A. Petway, Nathaniel Sherrill
Abstract
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.
