“…Neutrinoless double-electron capture ( 71), (A, Z)+2e − → (A, Z −2) was of interest as an attractive alternative to 0νββ decay, since there was the possibility of a resonant enhancement if the initial and final-state energies are close to degenerate (72). However, precise measurements of the involved nuclear masses disfavor this option (73,74). In addition, the decay to excited states, neutrinoless double-positron decay, or various combinations of electron capture and beta or positron decay suffer from very low rates.…”

Keywords lepton-number violation, neutrinos, beyond the Standard Model AbstractNeutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition whose observation would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. In this review, we summarize the theoretical progress to understand this process, the expectations and implications under various particle physics models, as well as the nuclear physics challenges that affect the precise predictions of the decay half-life. We will also provide a synopsis of the current and future large-scale experiments that aim at discovering this process in physically well-motivated half-life ranges.

“…Many areas of fundamental physics require the knowledge of mass differences or mass ratios of a variety of nuclides with very low uncertainty [1,2]. Notable examples are, e.g., neutrino physics [3], a test of special relativity [4] and bound-state quantum electrodynamics (QED) [5], ion clocks [6] and the search for Dark Matter via high-resolution isotope shift measurements [7][8][9]. In order to satisfy these requirements, the novel experiment PENTATRAP [10,11] has been set up at the Max Planck Institute for Nuclear Physics in Heidelberg.…”

First ever measurements of the ratios of free cyclotron frequencies of heavy highly charged ions with Z > 50 with relative uncertainties close to 10 −11 are presented. Such accurate measurements have become realistic due to the construction of the novel cryogenic multi-Penning-trap mass spectrometer PENTATRAP. Based on the measured frequency ratios, the mass differences of five pairs of stable xenon isotopes, ranging from 126 Xe to 134 Xe, have been determined. Moreover, the first direct measurement of an electron binding energy in a heavy highly charged ion, namely of the 37 th atomic electron in xenon, with an uncertainty of a few eV is demonstrated. The obtained value agrees with the calculated one using two independent different implementations of the multiconfiguration Dirac-Hartree-Fock method. PENTATRAP opens the door to future measurements of electron binding energies in highly charged heavy ions for more stringent tests of bound-state quantum electrodynamics in strong electromagnetic fields and for an investigation of the manifestation of Light Dark Matter in isotopic chains of certain chemical elements.
