Description
Unique forbidden β-decays have recently emerged as powerful probes of physics beyond the Standard Model, providing increased sensitivity to exotic weak interactions and right-handed couplings, and are now the focus of growing experimental efforts in the US and internationally. In this talk, I will present our recent study revealing that radiative corrections enable unique forbidden decays at vanishing nuclear recoil momentum, which were forbidden at tree level, leading to a dramatic change in the decay spectrum that was not anticipated in existing studies. I will discuss the implications for precision tests of the Standard Model and highlight the new opportunities this presents for probing light new physics, which is inaccessible in allowed decays, opening up a new regime of BSM physics within precision β-decay searches.
