Description

Extracting particle physics properties from neutrinoless double-beta (0nßß) decay, requires a detailed understanding of the involved nuclear structures. Still, modern calculations of the corresponding nuclear matrix elements (NMEs) differ by factors 2-3.

The high momentum transfer of Ordinary Muon Capture (OMC) provides insight into highly excited states similar to those that contribute virtually to 0nßß transitions.
The precise study of the gammas following the OMC process, makes this a promising tool to validate NME calculations, and test the quenching of the axial vector coupling g_A.

The MONUMENT collaboration is performing a series of explorative OMC measurements involving typical ßß decay daughter isotopes such as Se76 and Ba136, as well as other benchmark isotopes. In this presentation the experiment carried out at the Paul Scherrer Institute and first results from the beam-time in 2021 will be presented.

This research is supported by the DFG Grant 448829699 and RFBR-DFG with project number 21-52-12040.
