Description
We investigate the phenomenological signatures of Lorentz and CPT symmetry violation within two-neutrino (2νββ) and neutrinoless (0νββ) double beta decay. Using the Standard-Model Extension (SME) framework, we analyze how Lorentz-violating operators distort standard decay rates. For 2νββ decay, these violations manifest as precise spectral distortions in the continuous electron energy spectrum. For 0νββ decay, Lorentz-violating terms can mimic a Majorana mass term. By correlating these modifications with the latest constraints from experimental data and projected half-life sensitivities, we establish competitive bounds on hundreds of SME coefficients which will be the first of their kind to be recorded in the literature.
