Abstract

We present the search for Lorentz violation in the double beta decay of Se82 with CUPID-0, using an exposure of 9.95 kg×yr. We found no evidence for the searched signal and set a limit on the isotropic components of the Lorentz violating coefficient of aa-of(3)<4.1×10-6 GeV (90% credible interval). This results is obtained with a Bayesian analysis of the experimental data and fully includes the systematic uncertainties of the model. This is the first limit on aâ-of(3) obtained with a scintillating bolometer, showing the potentiality of this technique.
