Description
In atoms and molecules, electron-nucleon and nucleon-nucleon interactions are sensitive to the electromagnetic, weak and strong forces. Hence, these systems can provide versatile laboratories for precision studies of fundamental symmetries and the searches for New Physics beyond the Standard Model of particle physics.
Until now, symmetry-violating measurements have been performed in only a few stable systems, putting constraints on physics at the TeV scale. Atomic parity violation experiments, for example, constitute our best low-energy test of the Standard Model, and measurements of stable molecules have provided the most stringent constraint to the electron Electric Dipole Moment (eEDM) to date.
This contribution will present a brief summary of different experimental efforts that are being pursued worldwide for the study of fundamental physics with atomic and molecular spectroscopy. The discussion will be focused on the new opportunities that can be explored at EPIC-ISOLDE using radioactive atoms and molecules. The exotic systems can contain heavy and deformed nuclei offering enhanced and, in some cases, unique sensitivity to explore symmetry-violation nuclear effects in addition to the possible existence of new fundamental particles and forces. Future precision studies of these systems at radioactive beam facilities could provide new opportunities in fundamental physics research, offering complementary probes to ongoing studies at high-energy colliders.
