Diagnosing Phase-Interference Valleys in LRSM Contributions to $0\nu\beta\beta$ with a Geometry-Based EFT Pipeline
Abstract
We present an automated framework to identify and classify phase-interference cancellations in neutrinoless double beta decay ($0\nu\beta\beta$) within left--right symmetric models (LRSMs) matched onto SMEFT/LEFT.Treating an interference-sensitive complex amplitude proxy $C_\star$ as a scalar field over two independent phase knobs, we construct high-resolution 2D phase maps and detect ``valleys'' defined by $|C_\star|
