Nuclear beta decay is possibly the most investigated of all weak interaction processes. It has served in the past as a convenient way through which some of the fundamental properties of the weak interaction were established. Beta decay provides still today a powerful testing ground for models of nuclear structure and offers a window to search for new physics beyond the standard electroweak model in processes involving the lightest quarks.
In this presentation, we will review the place of nuclear beta decay in searches for new physics highlighting some remarkable results. The presentation will also discuss current activities involving high-precision measurements of beta-decay observables.
