When a muon binds with a deuteron, it forms a system with two neutrons in a process analogous to proton-proton fusion. Nuclear theorists examined this muon capture process to quantify theoretical uncertainty relevant for comparison with experimental data and to test predictions involving proton-proton fusion. The study supports ongoing efforts to enhance the accuracy of muon capture measurements and to apply the same theoretical framework to other processes.
