A Levitated-Magnet Vector Force Sensor for Spin-Dependent Exotic Interactions
Dorian W. P. Amaral, Lei Cong, Tim M. Fuchs +2
We present a magnetically levitated ferromagnetic vector force sensor that enables selective searches for spin-dependent exotic interactions mediated by beyond-Standard-Model boson…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
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…
Constraints on new vector boson mediated electron-nucleus interactions from spectroscopy of polar diatomic molecules
Konstantin Gaul, Lei Cong, Dmitry Budker
A measurement of parity violation in the hyperfine structure of BaF [E. Altuntaş et al. Phys. Rev. Lett. 120, 142501 (2018)] is reinterpreted with electronic structu…
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…
New Constraints on Axion Mediated Dipole-Dipole Interactions
Zitong Xu, Xing Heng, Guoqing Tian +5
The search for axions sits at the intersection of solving critical problems in fundamental physics, including the strong CP problem in QCD, uncovering the nature of dark matter, an…
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…
Spin-dependent exotic interactions
Lei Cong, Wei Ji, Pavel Fadeev +8
Novel interactions beyond the four known fundamental forces in nature (electromagnetic, gravitational, strong and weak interactions), may arise due to "new physics" beyond the stan…
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.},…
Axion-Like Particle Detection in Alkali-Noble-Gas Haloscopes
Xiaofei Huang, Xiaolin Ma, Lei Cong +4
Revealing the essence of dark matter (DM) and dark energy is essential for understanding our universe. Ultralight (rest energy 10 eV) bosonic particles, including pseudoscalar a…
