Description
Executive Summary
The present contribution stresses the importance and potential impact of low energy precision experiments for probing Beyond the Standard Model (BSM) physics at radioactive beam facilities for the next decade. Correlation experiments including MORA and WISArD, as well as precision beta spectrum shape measurements, like b-STILED, are currently ongoing, and new experiments using also radioactive molecules are being considered. These require installations that can produce radioactive beams in atomic or molecular form for isotopes of particular interest, mostly close to stability. Beams must be intense and pure, which can possibly be bunched, cooled and trapped, and in certain cases polarized. Currently, JYFL, ISOLDE/VITO, GANIL/DESIR and ISOL@MYRRHA are facilities that are expected to make a visible impact in BSM physics from such experiments, provided that enough time and effort are dedicated. In parallel, dedicated theory support via the application of modern effective field theories has to be pursued, following the recent and remarkable progress to bridge the gap between experiments at high and at low energies, in a comprehensive analysis of the nuclear beta-decay data.
