Testing Exotic Electron-Electron Interactions with the Helium Ionization-Energy Anomaly
Lei Cong, Filip Ficek, Rinat Abdullin +2
Precision atomic spectroscopy provides a sensitive probe of physics beyond the Standard Model. A recently reported theory-experiment discrepancy in the ionization energy of me…
Searching for Exotic Interactions between Antimatter
Lei Cong, Filip Ficek, Pavel Fadeev +2
We show that atomic antimatter spectroscopy can be used to search for new bosons that carry spin-dependent exotic forces between antifermions. A comparison of a recent precise meas…
Constraints on exotic interactions from scalar spin-spin coupling in tritium deuteride (DT)
Lei Cong, Derek F. Jackson Kimball, Mikhail G. Kozlov +1
A comparison of theoretical and experimental values of the scalar spin-spin interaction (-coupling) in tritium deuteride molecules yield constraints for nucleon-nucleon exotic i…
Improved constraints on exotic interactions between electron and proton in hydrogen
Lei Cong, Filip Ficek, Pavel Fadeev +1
Atomic spectroscopy can be used to search for new bosons that carry exotic forces between elementary fermions. A comparison of a recent precise measurement [Bullis \textit{et al.},…
