Stringent Constraints on New Pseudoscalar & Vector Bosons from Precision Hyperfine Splitting Measurements
Cedric Quint, Fabian HeiÃe, Joerg Jaeckel +3
Axion-like particles and similar new pseudoscalar as well as vector bosons coupled to nucleons and electrons are predicted to lead to spin-dependent forces in atoms and ions. We ar…

Limits on New Lorentz-violating Bosons
P. Carenza, J. Jaeckel, G. Lucente +3
We obtain novel constraints on new scalar fields interacting with Standard Model fermions through Lorentz-violating couplings, bridging searches for scalar particles and Lorentz-sy…
