Spurious Isospin Breaking in the In-medium Similarity Renormalization Group Open
Robustly quantifying the uncertainty in the isospin-related theoretical correction $δ_C$ to superallowed beta decay rates is vital for a correct assessment of CKM unitarity. To this end, we identify the sources of artificial or \textit{spu…
