First Search for Lorentz and CPT Violation in Double Beta Decay with EXO-200

Abstract

A search for Lorentz- and CPT-violating signals in the double beta decay spectrum of ${}^{136}$Xe has been performed using an exposure of 100 kg$\cdot$yr with the EXO-200 detector. No significant evidence of the spectral modification due to isotropic Lorentz-violation was found, and a two-sided limit of $-2.65\times 10^{-5}\text{GeV}<{\mathring{a}}_{\text{of}}^{(3)}<7.60\times 10^{-6}\text{GeV}$ (90% C.L.) is placed on the relevant coefficient within the Standard-Model Extension (SME). This is the first experimental study of the effect of the SME-defined oscillation-free and momentum-independent neutrino coupling operator on the double beta decay process.
