“…The method has been applied primarily to the computation of nuclear spectra and transitions among low-lying states, but also has been used to compute, e.g. cross sections for photo-excitation (Hagen et al 2014, Bonaiti et al 2022). And recently, the method was applied to the matrix element for the neutrinoless double-beta decay of 48 Ca (Novario et al 2021), a problem that resembles those addressed in this paper.…”

Molecules containing short-lived, radioactive nuclei are uniquely positioned to enable a wide range of scientific discoveries in the areas of fundamental symmetries, astrophysics, nuclear structure, and chemistry. Recent advances in the ability to create, cool, and control complex molecules down to the quantum level, along with recent and upcoming advances in radioactive species production at several facilities around the world, create a compelling opportunity to coordinate and combine these efforts to bring precision measurement and control to molecules containing extreme nuclei. In this manuscript, we review the scientific case for studying radioactive molecules, discuss recent atomic, molecular, nuclear, astrophysical, and chemical advances which provide the foundation for their study, describe the facilities where these species are and will be produced, and provide an outlook for the future of this nascent field.

“…Like all ab initio approaches, it can be made exact by allowing threebody, four-body, etc., operators to excite particles as well. The method has been applied primarily to the computation of nuclear spectra and transitions among low-lying states, but also has been used to compute, e.g., cross sections for photo-excitation (Hagen et al, 2014;Bonaiti et al, 2022).

“…Estimates of the effects of the higherbody operators allow make uncertainty analysis possible. The method has been used mainly to compute nuclear spectra and transition rates but also is being applied to other phenomena, e.g., for photo-excitation reactions [104,105]. Recently, it was used in a calculation of the the neutrinoless double-beta decay matrix element for 48 Ca [106], an observable that has features in common with…”

Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well beyond those reached directly at high energy colliders. Discrimination between different physics models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics. In this report, we discuss the current status and prospects in the near future for a compelling suite of such experiments, along with developments needed in the encompassing theoretical framework.
