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…
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.},…
Constraints on Spin-Spin-Velocity-Dependent Interaction
Wei Ji, Weipeng Li, Pavel Fadeev +5
The existence of exotic spin-dependent forces may shine light on new physics beyond the Standard Model. We utilize two iron shielded SmCo electron-spin sources and two opticall…
Sensitivity of Th nuclear clock transition to variation of the fine-structure constant
Pavel Fadeev, Julian C. Berengut, Victor V. Flambaum
Peik and Tamm [Europhys. Lett. 61, 181 (2003)] proposed a nuclear clock based on the isomeric transition between the ground state and the first excited state of thorium-229. This t…
Constraints on exotic spin-dependent interactions between matter and antimatter from antiprotonic helium spectroscopy
Filip Ficek, Pavel Fadeev, Victor V. Flambaum +4
Heretofore undiscovered spin-0 or spin-1 bosons can mediate exotic spin-dependent interactions between standard-model particles. Here we carry out the first search for semileptonic…
