    The study of β-decay is important to answer open questions in physics and astrophysics; however, theoretical predictions of the associated half-lives are still plagued by uncertainties. In this short review, we argue that a reliable model for this study is nuclear DFT, complemented by further specific correlations: the model, called Quasiparticle-Vibration Coupling (QPVC), has been successful in predicting half-lives in a number of spherical nuclei and the extenssion to deformed systems should be envisioned. Some remaining open questions will be addressed.
